如果您没有.PBO文件：

C＃

public int GetLineNumber(Exception ex)
{
    var lineNumber = 0;
    const string lineSearch = ":line ";
    var index = ex.StackTrace.LastIndexOf(lineSearch);
    if (index != -1)
    {
        var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
        if (int.TryParse(lineNumberText, out lineNumber))
        {
        }
    }
    return lineNumber;
}

Vb.net

Public Function GetLineNumber(ByVal ex As Exception)
    Dim lineNumber As Int32 = 0
    Const lineSearch As String = ":line "
    Dim index = ex.StackTrace.LastIndexOf(lineSearch)
    If index <> -1 Then
        Dim lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length)
        If Int32.TryParse(lineNumberText, lineNumber) Then
        End If
    End If
    Return lineNumber
End Function

或者作为Exception类的扩展

public static class MyExtensions
{
    public static int LineNumber(this Exception ex)
    {
        var lineNumber = 0;
        const string lineSearch = ":line ";
        var index = ex.StackTrace.LastIndexOf(lineSearch);
        if (index != -1)
        {
            var lineNumberText = ex.StackTrace.Substring(index + lineSearch.Length);
            if (int.TryParse(lineNumberText, out lineNumber))
            {
            }
        }
        return lineNumber;
    }
}

Answer 5

有效：

var LineNumber = new StackTrace(ex, True).GetFrame(0).GetFileLineNumber();

Answer 6

检查一下

StackTrace st = new StackTrace(ex, true);
//Get the first stack frame
StackFrame frame = st.GetFrame(0);

//Get the file name
string fileName = frame.GetFileName();

//Get the method name
string methodName = frame.GetMethod().Name;

//Get the line number from the stack frame
int line = frame.GetFileLineNumber();

//Get the column number
int col = frame.GetFileColumnNumber();

Answer 7

我在Exception上添加了扩展名，该扩展名返回行，列，方法，文件名和消息：

public static class Extensions
{
    public static string ExceptionInfo(this Exception exception)
    {

        StackFrame stackFrame = (new StackTrace(exception, true)).GetFrame(0);
        return string.Format("At line {0} column {1} in {2}: {3} {4}{3}{5}  ",
           stackFrame.GetFileLineNumber(), stackFrame.GetFileColumnNumber(),
           stackFrame.GetMethod(), Environment.NewLine, stackFrame.GetFileName(),
           exception.Message);

    }
}

Answer 8

我尝试使用@ davy-c解决方案，但出现异常“ System.FormatException：'输入字符串的格式不正确。'”，这是由于在行号之后仍存在文本，因此我进行了修改他发布并提出的代码：

int line = Convert.ToInt32(objErr.ToString().Substring(objErr.ToString().IndexOf("line")).Substring(0, objErr.ToString().Substring(objErr.ToString().IndexOf("line")).ToString().IndexOf("\r\n")).Replace("line ", ""));

这在VS2017 C＃中对我有效。

Answer 9

更新回答

    // 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(st.FrameCount-1);
    // Get the line number from the stack frame
    var line = frame.GetFileLineNumber();

Answer 10

扩展方法

static class ExceptionHelpers
{
    public static int LineNumber(this Exception ex)
    {
        int n;
        int i = ex.StackTrace.LastIndexOf(" ");
        if (i > -1)
        {
            string s = ex.StackTrace.Substring(i + 1);
            if (int.TryParse(s, out n))
                return n;
        }
        return -1;
    }
}

用法

try
{
    throw new Exception("A new error happened");
}
catch (Exception ex)
{
    //If error in exception LineNumber() will be -1
    System.Diagnostics.Debug.WriteLine("[" + ex.LineNumber() + "] " + ex.Message);
}

Answer 12

如果使用调试符号编译生成异常的库，行号将包含在堆栈跟踪中。这可以是单独的文件 (*.pdb) 或嵌入到库中。

对于 .NET Core、.NET 5 及更高版本，要在发布版本中具有完整的异常行号，请按如下方式配置项目：

<PropertyGroup>    
  <DebugSymbols>true</DebugSymbols>
  <DebugType>embedded</DebugType>

    <!-- Only enable the following if the line numbers mismatch -->
    <!--<Optimize>false</Optimize>-->
    
    <!--
      Additional properties which may impact how printed line numbers match the source code line numbers are listed here:
      https://docs.microsoft.com/en-us/dotnet/core/run-time-config/compilation
    -->
</PropertyGroup>

上述配置将直接在构建文件中包含调试符号，可以将其发布为 nuget。

上述替代方法是将调试包与主要 nuget 包一起恢复，目前尚不支持：https://github.com/NuGet/Home/issues/9667

现在获取异常行号：

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();
}

这对我有用：

try
{
  //your code;
}
catch(Exception ex)
{
  MessageBox.Show(ex.StackTrace + " ---This is your line number, bro' :)", ex.Message);
}
