[Mono-dev] Setting Assembly's Attributes / Injecting new attributes

[Jb Evain]

Hi,

It's pretty easy to change such a value.

foreach (CustomAttribute ca in asm.CustomAttributes) {
	if (ca.Constructor.DeclaringType.Name != "AssemblyNameAttribute")
		continue;

	ca.ConstructorParameters [0] = "Hello World";
}

If you want to add a new one, just create a fully constructed 
CustomAttribute instance to the collection, and save the assembly.
