C#教程之C# 动态获取代码所在行号

当前位置:

通过System.Diagnostics.StackTrace获取代码所在行号和文件信息

获取行号信息

复制代码

/// <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;

}

复制代码

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

复制代码

/// <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;

}

复制代码

获取Exception中行号

int lineNum = ex.StackTrace.IndexOf("行号");
