给定 .NET 中的 Type 对象，我可以获取源代码文件名吗？我知道这只能在 Debug 版本中使用，这很好，我也知道我可以使用 StackTrace 对象来获取调用堆栈中特定帧的文件名，但这不是我想要的。

但是我有可能获得给定 System.Type 的源代码文件名吗？

I encountered a similar problem. I needed to found the file name and line number of a specific method with only the type of the class and the method name. I'm on an old mono .net version (unity 4.6). I used the library cecil, it provide some helper to analyse your pbd (or mdb for mono) and analyse debug symbols. https://github.com/jbevain/cecil/wiki

For a given type and method:

System.Type myType = typeof(MyFancyClass);
string methodName = "DoAwesomeStuff";

I found this solution:

Mono.Cecil.ReaderParameters readerParameters = new Mono.Cecil.ReaderParameters { ReadSymbols = true };
Mono.Cecil.AssemblyDefinition assemblyDefinition = Mono.Cecil.AssemblyDefinition.ReadAssembly(string.Format("Library\\ScriptAssemblies\\{0}.dll", assemblyName), readerParameters);

string fileName = string.Empty;
int lineNumber = -1;

Mono.Cecil.TypeDefinition typeDefinition = assemblyDefinition.MainModule.GetType(myType.FullName);
for (int index = 0; index < typeDefinition.Methods.Count; index++)
{
    Mono.Cecil.MethodDefinition methodDefinition = typeDefinition.Methods[index];
    if (methodDefinition.Name == methodName)
    {
        Mono.Cecil.Cil.MethodBody methodBody = methodDefinition.Body;
        if (methodBody.Instructions.Count > 0)
        {
            Mono.Cecil.Cil.SequencePoint sequencePoint = methodBody.Instructions[0].SequencePoint;
            fileName = sequencePoint.Document.Url;
            lineNumber = sequencePoint.StartLine;
        }
    }
}

I know it's a bit late :) but I hope this will help somebody!

我使用这样的代码从正在运行的方法中获取源文件和行号：

//must use the override with the single boolean parameter, set to true, to return additional file and line info

System.Diagnostics.StackFrame stackFrame = (new System.Diagnostics.StackTrace(true)).GetFrames().ToList().First();

//Careful:  GetFileName can return null even though true was specified in the StackTrace above.  This may be related to the OS on which this is running???

string fileName = stackFrame.GetFileName();
string process = stackFrame.GetMethod().Name + " (" + (fileName == null ? "" : fileName + " ") + fileLineNumber + ")";

考虑到至少 C# 支持部分类声明（例如，public partial class Foo在两个源代码文件中），“给定 System.Type 的源代码文件名”是什么意思？如果一个类型声明分布在同一个程序集中的多个源代码文件中，则源代码中没有一个点是声明开始的地方。

@Darin Dimitrov：这看起来不像“如何获取源文件名和类型成员的行号？”的重复。对我来说，因为那是关于 type member，而这个问题是关于type。
