添加项目到ObjectListView

我的程序提取Windows更新，检测版本号并将它们记录到列表视图中的列(KB, version)，但我试图将其更改为ObjectListView，以便我可以对列进行排序。我不能为我的生活工作出如何写一个ObjectListView的结果，没有我尝试似乎工作。下面是我当前的代码:

foreach (string file in msu)
{
    string KB = GetKBNumber(file);
    Expand.MSU(file, TempDirectory + "''" + KB);
    List<string> versions = GetVersionNumbers(TempDirectory + "''" + KB);
    foreach (string version in versions)
    {
        ListViewItem itm = new ListViewItem(new[] { KB, version });
        olvOutput.Items.Add(itm);
    }
    PerformStep();
}

但是它只是将空白数据写入控件。我做错了什么?提前谢谢。

编辑:这是olvOutput设计器代码:

        // 
        // olvOutput
        // 
        this.olvOutput.AllColumns.Add(this.olvKBNumber);
        this.olvOutput.AllColumns.Add(this.olvVersion);
        this.olvOutput.Anchor = ((System.Windows.Forms.AnchorStyles)((((System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) 
        | System.Windows.Forms.AnchorStyles.Left) 
        | System.Windows.Forms.AnchorStyles.Right)));
        this.olvOutput.Columns.AddRange(new System.Windows.Forms.ColumnHeader[] {
        this.olvKBNumber,
        this.olvVersion});
        this.olvOutput.Location = new System.Drawing.Point(18, 12);
        this.olvOutput.Name = "olvOutput";
        this.olvOutput.ShowGroups = false;
        this.olvOutput.Size = new System.Drawing.Size(571, 193);
        this.olvOutput.TabIndex = 8;
        this.olvOutput.UseAlternatingBackColors = true;
        this.olvOutput.UseCompatibleStateImageBehavior = false;
        this.olvOutput.View = System.Windows.Forms.View.Details;
        // 
        // olvKBNumber
        // 
        this.olvKBNumber.AspectName = "";
        this.olvKBNumber.CellPadding = null;
        this.olvKBNumber.MaximumWidth = 100;
        this.olvKBNumber.MinimumWidth = 100;
        this.olvKBNumber.Text = "KB Number";
        this.olvKBNumber.Width = 100;
        // 
        // olvVersion
        // 
        this.olvVersion.AspectName = "";
        this.olvVersion.CellPadding = null;
        this.olvVersion.Text = "Version";
        this.olvVersion.Width = 113;

foreach (string file in msu)
{
    string KB = GetKBNumber(file);
    Expand.MSU(file, TempDirectory + "''" + KB);
    List<string> versions = GetVersionNumbers(TempDirectory + "''" + KB);
    foreach (string version in versions)
    {
        olvOutput.AddObject(new { kbAspectName = KB, versionAspectName = version });
    }
    PerformStep();
}

// 
// olvKBNumber
// 
this.olvKBNumber.AspectName = "kbAspectName";
// ...
// 
// olvVersion
// 
this.olvVersion.AspectName = "versionAspectName";
