C＃通过Excel工作簿中搜索

我想用C＃查找文本（组装）的特定刺痛。我这个小码所著搜索一个excel文件：C＃通过Excel工作簿中搜索

private void button1_Click(object sender, EventArgs e) 
{ 
    string File_name = "C:\\test.xls"; 
    Microsoft.Office.Interop.Excel.Application oXL = new Microsoft.Office.Interop.Excel.Application(); 
    Microsoft.Office.Interop.Excel.Workbook oWB; 
    Microsoft.Office.Interop.Excel.Worksheet oSheet; 
    try 
    { 
     object missing = System.Reflection.Missing.Value; 
     oWB = oXL.Workbooks.Open(File_name, missing, missing, missing, missing, 
      missing, missing, missing, missing, missing, missing, 
      missing, missing, missing, missing); 
     oSheet = (Microsoft.Office.Interop.Excel.Worksheet)oWB.Worksheets[3]; 
     Microsoft.Office.Interop.Excel.Range oRng = GetSpecifiedRange("ASSEMBLY", oSheet); 
     if (oRng != null) 
     { 
      MessageBox.Show("Text found, position is Row:" + oRng.Row + " and column:" + oRng.Column); 
     } 
     else 
     { 
      MessageBox.Show("Text is not found"); 
     } 
     oWB.Close(false, missing, missing); 

     oSheet = null; 
     oWB = null; 
     oXL.Quit(); 
    } 
    catch (Exception ex) 
    { 

    } 
} 
private Microsoft.Office.Interop.Excel.Range GetSpecifiedRange(string matchStr, Microsoft.Office.Interop.Excel.Worksheet objWs) 
{ 
    object missing = System.Reflection.Missing.Value; 
    Microsoft.Office.Interop.Excel.Range currentFind = null; 
    Microsoft.Office.Interop.Excel.Range firstFind = null; 
    currentFind = objWs.get_Range("A1", "AM100").Find(matchStr, missing, 
        Microsoft.Office.Interop.Excel.XlFindLookIn.xlValues, 
        Microsoft.Office.Interop.Excel.XlLookAt.xlPart, 
        Microsoft.Office.Interop.Excel.XlSearchOrder.xlByRows, 
        Microsoft.Office.Interop.Excel.XlSearchDirection.xlNext, false, missing, missing); 
    return currentFind; 

}

该工程确定，就可以找到工作簿中给定的字符串。但是，该工作簿有很多工作表，现在我只搜索一个（表3）。如何搜索整个工作簿？

另外，这个excel文件有很多次“ASSEMBLY”这个词。如何继续搜索并显示所有结果，而不仅仅是第一个？

您专门询问表3 ..所以这就是你正在寻找 – Rob

要搜索每个表，迭代他们：'的foreach（Excel.Worksheet片oWB.Worksheets）{...}'。要继续搜索致电'.FindNext' –

希望你的帖子能为你的问题实现的答案...谢谢 – sam

k = 1; 
do { 
    oSheet = (Microsoft.Office.Interop.Excel.Worksheet)oWB.Worksheets[k]; 
} while (k <= oWB.Worksheets.Count);
