C# emit call to generic method
Having the class
class C
{
public T Get<T>()
{
return default;
}
public void M()
{
int i = this.Get<Int32>();
}
}
I want to generate the body of M at runtime using Reflection.Emit and ILGenerator so that it exactly resembles what is shown above.
What I tried is
ilGenerator.Emit(OpCodes.Ldarg_0);
ilGenerator.Emit(OpCodes.Call, typeof(C).GetMethod(nameof(C.Get), BindingFlags.Instance));
which yields
ldarg.0
call instance !!0 C::Get<M0>(string)
// ^^
ret
but I need to get
ldarg.0
call instance !!0 C::Get<int32>(string)
// ^^^^^
ret
(note the different type parameters in the call to C.Get<T>)
When emitting a call to a generic cfunction, how do I pass the type of the generic parameter (i.e. get rid of the M0 and have it say int32 instead)?

You need to substitute the type arguments with MakeGenericMethod:
ilGenerator.Emit(OpCodes.Ldarg_0);
ilGenerator.Emit
(
OpCodes.Call,
typeof(C)
.GetMethod(nameof(C.Get), BindingFlags.Instance)
.MakeGenericMethod(typeof(int))
);
