问题描述

在 catch 块中，如何获取引发异常的行号?

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

推荐答案

如果您需要的不仅仅是从 Exception.StackTrace 获得的格式化堆栈跟踪的行号，您可以使用 StackTrace 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，这仅在有可用于程序集的 pdb 文件时才有效.

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