Excel 自动化:范围查找

本文关键字：查找 范围 自动化 Excel | 更新日期: 2023-09-27 17:57:23

我想在我的 c# 程序中实现此方法。但是我在一行中填写适当的参数时遇到问题，例如

long FirstRow = myWorksheet.Cells.Find(
  What:="*", 
  After:=Range("IV65536"), 
  LookIn:=xlValues,
  LookAt:= xlPart, 
  SearchOrder:=xlByRows,
  SearchDirection:=xlNext).Row

下面是 Range.Find 方法的文档。

Range Find(
    [In] object What, 
    [In, Optional] object After, 
    [In, Optional] object LookIn, 
    [In, Optional] object LookAt, 
    [In, Optional] object SearchOrder, 
    [In, Optional] XlSearchDirection SearchDirection, 
    [In, Optional] object MatchCase, 
    [In, Optional] object MatchByte, 
    [In, Optional] object SearchFormat
);

所以基本上我不知道如何制作适当的参数对象。

更新 Excel.范围范围;

        object What = "*";
        object After = xlWorkSheet.get_Range("A1", "IV65536");
        object LookIn = "xlValues";
        object LookAt = "xlPart";
        object SearchOrder = "xlByRows";
        Excel.XlSearchDirection SearchDirection = Excel.XlSearchDirection.xlNext;
        object MatchCase = System.Reflection.Missing.Value;
        object MatchByte = System.Reflection.Missing.Value;
        object SearchFormat = System.Reflection.Missing.Value;
        range = xlWorkSheet.Cells.Find(
            What,
            After,
            LookIn,
            LookAt,
            SearchOrder,
            SearchDirection,
            MatchCase,
            MatchByte,
            SearchFormat
            );

给出"COMException 未处理：类型不匹配。（HRESULT的例外：0x80020005（DISP_E_TYPEMISMATCH））"

更新 #2这是到目前为止的方法。唯一缺少的是设置并返回范围。

    public void RealUsedRange()
    {
        int FirstRow = xlWorkSheet.Cells.Find(
            "*",
            xlWorkSheet.get_Range("IV65536", misValue),
            Excel.XlFindLookIn.xlValues,
            Excel.XlLookAt.xlPart,
            Excel.XlSearchOrder.xlByRows,
            Excel.XlSearchDirection.xlNext,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value
            ).Row;
        int FirstColumn = xlWorkSheet.Cells.Find(
            "*",
            xlWorkSheet.get_Range("IV65536", misValue),
            Excel.XlFindLookIn.xlValues,
            Excel.XlLookAt.xlPart,
            Excel.XlSearchOrder.xlByColumns,
            Excel.XlSearchDirection.xlNext,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value
            ).Column;
        int LastRow = xlWorkSheet.Cells.Find(
            "*",
            xlWorkSheet.get_Range("IV65536", misValue),
            Excel.XlFindLookIn.xlValues,
            Excel.XlLookAt.xlPart,
            Excel.XlSearchOrder.xlByRows,
            Excel.XlSearchDirection.xlPrevious,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value
            ).Row;
        int LastColumn = xlWorkSheet.Cells.Find(
            "*",
            xlWorkSheet.get_Range("IV65536", misValue),
            Excel.XlFindLookIn.xlValues,
            Excel.XlLookAt.xlPart,
            Excel.XlSearchOrder.xlByColumns,
            Excel.XlSearchDirection.xlPrevious,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value,
            System.Reflection.Missing.Value
            ).Column;
    }

Excel 自动化:范围查找

未经过测试，但这给了你一个大致的想法：

long firstRow = myWorkSheet.Cells.Find(
    "*", /* What */
    Range("IV65536"), /* After */
    Excel.XlFindLookIn.xlValues, /* LookIn */
    Excel.XlLookAt.xlPart, /* LookAt */
    Excel.XlSearchOrder.xlByRows, /* SearchOrder */
    Excel.XlSearchDirection.xlNext, /* SearchDirection */
    Type.Missing, /* MatchCase */
    Type.Missing, /* MatchByte */
    Type.Missing /* SearchFormat */
    ).Row;

由于不能在没有 C# v4 的情况下使用 VB.NET 的可选参数语法，因此需要按顺序提供所有参数。 提供null可能适用于缺少的参数，但我很确定Type.Missing是正确的填充物。 除此之外，它只是像你期望的那样称呼它。

下面是一些完整的 C# 示例：

  • 如何：在工作表区域中搜索文本

下一个问题是 LookIn、LookAt 和 SearchOrder 参数。它们不应该是一个字符串，而类似于 SearchDirection 参数：

object What = "*";
object After = xlWorkSheet.get_Range("A1", "IV65536");
object LookIn = Excel.XlFindLookIn.xlValues;
object LookAt = Excel.XlLookAt.xlPart;
object SearchOrder = Excel.XlSearchOrder.xlByRows;
Excel.XlSearchDirection SearchDirection = Excel.XlSearchDirection.xlNext;
object MatchCase = System.Reflection.Missing.Value;
object MatchByte = System.Reflection.Missing.Value;
object SearchFormat = System.Reflection.Missing.Value;
range = xlWorkSheet.Cells.Find(
    What,
    After,
    LookIn,
    LookAt,
    SearchOrder,
    SearchDirection,
    MatchCase,
    MatchByte,
    SearchFormat
);
