C＃：工作簿另存爲以宏保存在它

Question

下面是我的代碼，我複製工作表，並保存爲新的文件，它實際上節省了沒有我的地方，我們有環境 Office 2003的宏，在Windows Server 2003

但在服務器將其與宏撲救，我不想 環境中的Office 2003，Windows Server 2008的

C＃：

try 
      { 
       wBook = xCel.Workbooks.Open(ExcelPath);     
       wSheet = (Excel.Worksheet)wBook.Worksheets.get_Item(1);      
       wSheet.Copy(Type.Missing, Type.Missing);      
       wSheet = (Excel.Worksheet)wBook.Sheets[1]; 
       wSheet.SaveAs(ExcelCopyPath); 
      } 

      catch {} 
      finally 
      {     
       if (wBook != null) 
       {      
        wBook.Close(); 
        wSheet = null; 
        wBook = null; 
        Thread.Sleep(500); 
       } 
       if (Excel.ProcessID > 0) 
       { 

        Process pxCel = Process.GetProcessById(Excel.ProcessID); 
        pxCel.Kill(); 
       } 

       GC.Collect(); 
       GC.WaitForPendingFinalizers(); 
       GC.Collect(); 
       GC.WaitForPendingFinalizers();     
       try { Marshal.FinalReleaseComObject(wSheet);} 
       catch {}           
       try { Marshal.FinalReleaseComObject(wBook);} 
       catch {}     
      } 

請檢查我的問題......並提出了一些答案。 感謝

登錄你的異常，像這樣：

try 
{ 
    wBook = xCel.Workbooks.Open(ExcelPath);     
    wSheet = (Excel.Worksheet)wBook.Worksheets.get_Item(1);      
    wSheet.Copy(Type.Missing, Type.Missing);      
    wSheet = (Excel.Worksheet)wBook.Sheets[1]; 
    wSheet.SaveAs(ExcelCopyPath); 
} 

catch(Exception ex) 
{ 
    using(var sw = new StreamWriter(@"C:\temp\mylog.txt", true)) 
    { 
     sw.WriteLine("First catch block"); 
     sw.WriteLine(ex.Message); 
    } 
} 
finally 
{     
    if (wBook != null) 
    {      
     wBook.Close(); 
     wSheet = null; 
     wBook = null; 
     Thread.Sleep(500); 
    } 
    if (Excel.ProcessID > 0) 
    { 

     Process pxCel = Process.GetProcessById(Excel.ProcessID); 
     pxCel.Kill(); 
    } 

    GC.Collect(); 
    GC.WaitForPendingFinalizers(); 
    GC.Collect(); 
    GC.WaitForPendingFinalizers();     
    try { Marshal.FinalReleaseComObject(wSheet);} 
catch(Exception ex) 
{ 
    using(var sw = new StreamWriter(@"C:\temp\mylog.txt", true)) 
    { 
     sw.WriteLine("Second catch block"); 
     sw.WriteLine(ex.Message); 
    } 
}          
    try { Marshal.FinalReleaseComObject(wBook);} 
catch(Exception ex) 
{ 
    using(var sw = new StreamWriter(@"C:\temp\mylog.txt", true)) 
    { 
     sw.WriteLine("Third catch block"); 
     sw.WriteLine(ex.Message); 
    } 
}    
} 

你真的應該使用像NLOG日誌框架，但這應該幫助你在短期內。這不會解決您的問題，但至少現在您可以打開C:\temp\mylog.txt並查看出了什麼問題，這將有助於您診斷問題。有了空的catch塊，你將永遠無法解決問題，因爲你永遠無法弄清楚出了什麼問題。
