在WinForms c#使用内置的.sort()方法排序ListView时，程序挂起(仅Visual Studio受影响

我有一些奇怪的问题与ListView拒绝正确排序自己。我在程序中99%的ListView上都使用了这个代码它们工作得很好。然而，对于一个ListView(它曾经工作过)，它拒绝工作挂起程序。当我在两种方法上都添加换行符时。它到达ListViewColumnSorter.columnClick(listViewKlienci, ref lvwColumnSorterKlienci, sender, e, headerIcons);，然后通过代码到达varListView.Sort();，然后停在这里。永远不会达到方法的终点。ListView非常简单，只有2列和一些颜色。

private void listViewKlienci_ColumnClick(object sender, ColumnClickEventArgs e) {
        ListViewColumnSorter.columnClick(listViewKlienci, ref lvwColumnSorterKlienci, sender, e, headerIcons);
        ListViewHelper.listViewResize(listViewKlienci);
}
public static void columnClick(ListView varListView, ref ListViewColumnSorter lvwColumnSorter, object sender, ColumnClickEventArgs e, ImageList headerImages) {
        //get list view header
        IntPtr hHeader = SendMessage(varListView.Handle, LVM_GETHEADER, IntPtr.Zero, IntPtr.Zero);
        SendMessage(hHeader, HDM_SETIMAGELIST, IntPtr.Zero, headerImages.Handle);
        SortOrder Order = SortOrder.Descending;
        //format icons
        HDITEM hd = new HDITEM {
                                   mask = HDI_IMAGE | HDI_FORMAT
                               };
        for (int i = 0; i < varListView.Columns.Count; i++) {
            //    if (i != e.Column) {
            hd.fmt = HDF_LEFT | HDF_STRING;
            hd.iImage = -1;
            SendMessage(hHeader, HDM_SETITEM, new IntPtr(i), ref hd);
            //    }
        }
        hd.fmt = HDF_LEFT | HDF_STRING | HDF_BITMAP_ON_RIGHT;
        ListViewHelper.enableDoubleBuffer(varListView);
        if (Order != SortOrder.None) {
            hd.fmt |= HDF_IMAGE;
        }
        if (e.Column == lvwColumnSorter.SortColumn) {
            if (lvwColumnSorter.Order == SortOrder.Ascending) {
                hd.iImage = 0;
                lvwColumnSorter.Order = SortOrder.Descending;
            } else {
                hd.iImage = 1;
                lvwColumnSorter.Order = SortOrder.Ascending;
            }
        } else {
            hd.iImage = 1;
            lvwColumnSorter.SortColumn = e.Column;
            lvwColumnSorter.Order = SortOrder.Ascending;
        }
        SendMessage(hHeader, HDM_SETITEM, new IntPtr(e.Column), ref hd);
        varListView.Sort();
    }

， Compare在Sort()中被大量执行。

    /// <summary>
    ///   This method is inherited from the IComparer interface.  It compares the two objects passed using a case insensitive comparison.
    /// </summary>
    /// <param name = "x">First object to be compared</param>
    /// <param name = "y">Second object to be compared</param>
    /// <returns>The result of the comparison. "0" if equal, negative if 'x' is less than 'y' and positive if 'x' is greater than 'y'</returns>
 public int Compare(object x, object y) {
        int compareResult;
        var listviewX = (ListViewItem) x;
        var listviewY = (ListViewItem) y;
        string s1 = listviewX.SubItems.Count > ColumnToSort ? listviewX.SubItems[ColumnToSort].Text : String.Empty;
        string s2 = listviewY.SubItems.Count > ColumnToSort ? listviewY.SubItems[ColumnToSort].Text : String.Empty;
        int i1;
        int i2;
        DateTime date1;
        DateTime date2;
        decimal d1;
        decimal d2;
        if (int.TryParse(s1, out i1) && int.TryParse(s2, out i2)) {
            compareResult = ObjectCompare.Compare(i1, i2);
        } else if (DateTime.TryParse(s1, out date1) && DateTime.TryParse(s2, out date2)) {
            compareResult = ObjectCompare.Compare(date1, date2);
        } else if (Locale.returnDecimalFromZl(s1, out d1) && Locale.returnDecimalFromZl(s2, out d2)) {
            compareResult = ObjectCompare.Compare(d1, d2);
        } else {
            compareResult = ObjectCompare.Compare(s1, s2);
        }
        // Calculate correct return value based on object comparison
        if (OrderOfSort == SortOrder.Ascending) {
            // Ascending sort is selected, return normal result of compare operation
            return compareResult;
        } else if (OrderOfSort == SortOrder.Descending) {
            // Descending sort is selected, return negative result of compare operation
            return (-compareResult);
        } else {
            // Return '0' to indicate they are equal
            return 0;
        }
    }

如果我改变代码一点，删除所有的If，只留下一个比较，它立即返回结果。

        //if (int.TryParse(s1, out i1) && int.TryParse(s2, out i2)) {
        //    compareResult = ObjectCompare.Compare(i1, i2);
        //} else if (DateTime.TryParse(s1, out date1) && DateTime.TryParse(s2, out date2)) {
        //    compareResult = ObjectCompare.Compare(date1, date2);
        //} else if (Locale.returnDecimalFromZl(s1, out d1) && Locale.returnDecimalFromZl(s2, out d2)) {
        //    compareResult = ObjectCompare.Compare(d1, d2);
        //} else {
            compareResult = ObjectCompare.Compare(s1, s2);
       // }

似乎这就是……的原因。但它在Visual Studio之外工作得很好，只是在Visual Studio中它会导致很大的减速。

我进一步开始添加更多的比较结果，只有最后一个导致放缓:

 public static bool returnDecimalFromZl(string dataToCheck, out decimal value) {
        if (dataToCheck.Trim() != "") { // && dataToCheck.Contains(" zł")) {
            try {
                value = Decimal.Parse(dataToCheck.Trim(), NumberStyles.Number | NumberStyles.AllowCurrencySymbol);
                return true;
            } catch {
                value = 0m;
                return false;
            }
        }
        value = 0m;
        return false;
    }

如果我把它改成:

    public static bool returnDecimalFromCurrency(string dataToCheck, out decimal value) {
        if ((dataToCheck.Trim() != "")  && (dataToCheck.Contains(" zł"))) {
            try {
                value = Decimal.Parse(dataToCheck.Trim(), NumberStyles.Number | NumberStyles.AllowCurrencySymbol);
                return true;
            } catch {
                value = 0m;
                return false;
            }
        }
        value = 0m;
        return false;
    }

它立即开始工作。这在方法上只有&& (dataToCheck.Contains(" zł"))。奇怪的东西!

EDIT1:有趣的是，在我让它运行5-10分钟后，它从Sort成功返回…

EDIT2。使用第一列排序可以工作。第二列保存人名(1200~人名)

EDIT3。排序以外的Visual Studio工作得很好(我去BIN目录在项目和执行我的应用程序排序在1秒)。所以似乎只有Visual Studio受到了影响。我甚至把我的旧硬盘放在我的电脑上，安装了不同(相同版本)的Visual Studio，问题仍然存在。

标引。如果我启动PROFILER，如RedGate ANTS PROFILER从Visual Studio问题不显示和ListView排序是非常快…$#^$*$#%

 public static bool returnDecimalFromZl(string dataToCheck, out decimal value) {
        if (dataToCheck.Trim() != "") { 
            try {
                value = Decimal.Parse(dataToCheck.Trim(), NumberStyles.Number | NumberStyles.AllowCurrencySymbol);
                return true;
            } catch {
                value = 0m;
                return false;
            }
        }
        value = 0m;
        return false;
    }

    public static bool returnDecimalFromZl(string dataToCheck, out decimal value) {
        if ((dataToCheck.Trim() != "")  && (dataToCheck.Contains(" zł"))) {
            try {
                value = Decimal.Parse(dataToCheck.Trim(), NumberStyles.Number | NumberStyles.AllowCurrencySymbol);
                return true;
            } catch {
                value = 0m;
                return false;
            }
        }
        value = 0m;
        return false;
    }
