debugging .net c#

我们使用 Debug.Assert 向开发人员发出代码问题的信号。我想添加发生错误的行号,但不硬编码,因为这可能会改变,我们将忘记更新字符串。

添加错误的行号会很方便。有什么想法吗?

   Debug.Assert

__FILE__ __LINE__ StackTrace

using System.Diagnostics;

namespace Managed
{
    class Program
    {
        static void Main(string[] args)
        {
            AssertWithCallSite(false, "Failed!");
        }

        [Conditional("DEBUG")]
        static void AssertWithCallSite(bool condition, string message)
        {
            if (!condition)
            {
                var callSite = (new StackTrace(1, true)).GetFrame(0);

                string fileName = callSite.GetFileName();
                int lineNumber = callSite.GetFileLineNumber();

                string assertMessage = string.Format(
                    "Assert at {0}:{1}:\n{2}",
                    fileName,
                    lineNumber,
                    message
                );

                Debug.Assert(false, assertMessage);
            }
        }
    }
}

Whats the equivalent of LINE and FILE in C#

string currentFile=new System.Diagnostics.StackTrace(true).GetFrame(0).GetFileName(); 
int currentLine = new System.Diagnostics.StackTrace(true).GetFrame(0).GetFileLineNumber();

StackTrace StackFrame System.Diagnostics

static string GetDiagnosticsInformationForCurrentFrame()
{
    StackTrace st = new StackTrace(new StackFrame(true));        
    StackFrame sf = st.GetFrame(1); // we want the frame from where this method was called

    return String.Format("File: {0}, Method: {1}, Line Number: {2}, Column Number: {3}", sf.GetFileName(), sf.GetMethod().Name, sf.GetFileLineNumber(), sf.GetFileColumnNumber());
}

Debug.Assert(true, "Unexpected error occurred at " + GetDiagnosticsInformationForCurrentFrame());

Conditional GetDiagnosticsInformationForCurrentFrame

UAP

 public static void Assert(bool val, string message,  [CallerFilePath] string file = "",  [CallerMemberName] string memberName = "", [CallerLineNumber] int lineNumber = 0)
    {
        string msg = String.Format($"File: {file}, Method: {memberName}, Line Number: {lineNumber}\n\n{message}");
        Debug.Assert(val, msg);


    }
