C＃ - 获取引发的异常行号 [英] C# - get line number which threw exception

问题描述

在抓块，我怎样才能得到它抛出一个异常？

In a catch block, how can I get the line number which threw an exception?

推荐答案

如果你需要的不仅仅是格式化的堆栈跟踪越多，你从Exception.StackTrace得到行号，可以使用的堆栈跟踪类：

If you need the line number for more than just the formatted stack trace you get from Exception.StackTrace, you can use the StackTrace class:

try
{
    throw new Exception();
}
catch (Exception ex)
{
    // Get stack trace for the exception with source file information
    var st = new StackTrace(ex, true);
    // Get the top stack frame
    var frame = st.GetFrame(0);
    // Get the line number from the stack frame
    var line = frame.GetFileLineNumber();
}

请注意，这只会工作，如果没有可用于装配一个PDB文件。

Note that this will only work if there is a pdb file available for the assembly.
