让你的代码输出exception发生时所在的文件名, 行号, 列号

代码如下:

try

{

    //Your Code Here

}

catch (Exception ex)

{

    Console.WriteLine(ex.Message);



    System.Diagnostics.StackTrace trace = 

        new System.Diagnostics.StackTrace(ex, true);

    Console.WriteLine(

        trace.GetFrame(trace.FrameCount - 1).GetMethod().Name);

    Console.WriteLine(

        trace.GetFrame(trace.FrameCount - 1).GetFileLineNumber());

    Console.WriteLine(

        trace.GetFrame(trace.FrameCount - 1).GetFileColumnNumber());

}

 

简单一点的, 可以使用Exception.ToString().

ex.ToString()的样例输出:

System.InvalidCastException: Unable to cast object of type 'Microsoft.SharePoint.SPList' to type 'Microsoft.SharePoint.SPDocumentLibrary'.
   at GetFolderLength.Program.Main(String[] args) in E:\code\csharp\project1\Program.cs:line 110

 

System.AppDomain.CurrentDomain.BaseDirectory.ToString()的结果如下:

E:\code\csharp\project1\bin\Debug\
