How to get the value of private field in C#?

Question

I ran into a problem that I need to access to private field of a class. For example:

class MyClass 
{
    private string someString;

    public MyClass( stri         


        

Answer 1

Here is a working generics version as clean as I can get it.

private static object GetInstanceField(T instance, string fieldName)
{                
    BindingFlags bindFlags = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static;
    FieldInfo field = typeof(T).GetField(fieldName, bindFlags);
    return field.GetValue(instance);
}

usage

var str = (string)GetInstanceField(instance, "someString");
