C# stack traces take the following form:

   at Foo.Core.Test.FinalMethod(Doh doh) in C:\Projects\src\Core.Tests\Test.cs:line 21
   at Foo.Core.Test.AnotherMethod(Bar bar)
   at Foo.Core.Test.AMethod() in C:\Projects\src\Core.Tests\Test.cs:line 6
   at Foo.Core.Test.<>c__DisplayClass7.<SomeAnonDelegate>b__6(Object _) in C:\Projects\src\Core.Tests\Test.cs:line 35

How can I retrieve namespace, class, method, file and line number from each line?

  • Are there any existing classes to do this?
  • If not what would be the the best approach?
  • Regex? How would I greedily match the namespace but leave the class and method?
  • Custom parser?

Would appreciate some ideas and input.

    If you’re getting this from a StackTrace, then you can loop through the StackFrames via GetFrame and call GetMethod, GetFileName, and GetFileLineNumber. Namespace and class can be retrieved from the method.

    EDIT
    In response to the first comment (unfortunately we get the traces from Exception.StackTrace), you can call the StackTrace(Exception) constructor.

    EDIT
    I should’ve linked to this constructor instead — StackTrace(Exception,bool).
