通过System.Diagnostics.StackTrace获取代码所在行号和文件信息
获取行号信息
/// <summary>
/// Get line number of code dynamically
/// </summary>
/// <param name="skipFrames">number of frames to skip</param>
/// <returns>line number of code after skipping frames</returns>
public static int GetCodeLineNum(int skipFrames)
{
StackTrace st = new StackTrace(skipFrames, true);
StackFrame fram = st.GetFrame(0);
int lineNum = fram.GetFileLineNumber();
return lineNum;
}
skipFrames == 0 ：
获取的是 System.Diagnostics.StackTrace st = new System.Diagnostics.StackTrace(skipFrames, true); 所在行号
skipFrames == 1：
获取的是函数GetCodeLineNum被调用时所在行号
获取文件路径信息
/// <summary>
/// Get file name information of code dynamically
/// </summary>
/// <param name="skipFrames">number of frames to skip</param>
/// <returns>file name information of code after skipping frames</returns>
public static string GetCodeFileName(int skipFrames)
{
StackTrace st = new StackTrace(skipFrames, true);
StackFrame fram = st.GetFrame(0);
string source = fram.GetFileName();
return source;
}
获取Exception中行号
int lineNum = ex.StackTrace.IndexOf("行号");
