Question

Let’s say that I have the following delegate:

public delegate void Example(); 

and a class such as the following:

public class TestClass {     Example FailingTest = () => Assert.Equal(0,1); } 

How can I use reflection to get the name ‘FailingTest’?

So far I have tried:

var possibleFields = typeof(TestClass).GetFields(relevant_binding_flags)                             .Where(x => x.FieldType.Equals(typeof(Example)));  foreach(FieldInfo oneField in possibleFields) {   // HERE I am able to access the declaring type name   var className = oneField.ReflectedType.Name; // == 'TestClass'    // but I am not able to access the field    // name 'FailingTest' because:   var fieldName = oneField.Name; // == 'CS$<>9__CachedAnonymousMethodDelegate1' } 

Stepping through in the debugger, I am unable to find a path to the name of the declared field, ‘FailingTest’.

Is that info retained at runtime or is it lost when the anonymous delegate is assigned?

Answer 1

What BindingFlags are you passing to GetFields? I used these:

BindingFlags.NonPublic | BindingFlags.Instance 

and I was able to see the name of the field.
