How to use local variable as a type? Compiler says “it is a variable but is used like a type”

At run-time, I don\'t know what type of variable v1 is. For this reason, I wrote many if else statements:

For generics, you have to create them dynamically.

MethodInfo method = typeof(Sample).GetMethod("GenericMethod");
MethodInfo generic = method.MakeGenericMethod(myType);
generic.Invoke(this, null);

To create a generic object, you can

var type = typeof(ShellProperty<>).MakeGenericType(typeof(SomeObject));
var v2 = Activator.CreateInstance(type);

Please refer to Initializing a Generic variable from a C# Type Variable
