Question

Using Reflection to set a static variable value before object's initialization? (C#)

Answer 1

+7 A:

For static values you can pass null for the instance parameter.

var type = typeof(SomeClass);
var field = type.GetField("SomeField");
field.SetValue(null, 42);

Sweet, thanks! I really appreciate it.

+1 fascinating : what I find a little scary in this technique is : if the field in question is readonly : this code will not cause a run-time error when executed.

If the field in question is read-only, does it just do nothing? Or does it set the value anyway? Is this just .NET 3.5?

Answer 2

+1 A:

could you create a static function that is public and use it to set your private static variable ?

I'm guessing this is against a type for which @Chance does not have source code.

extension method ?

Extension methods cannot access private data. http://msdn.microsoft.com/en-us/library/bb383977.aspx
