[英]C# Open generic type comparison. Generic<> is “parent” of Generic<T>?
I have a class MyGeneric<T>, and some cached data created from type MyGeneric<string>, MyGeneric<int>, MyGeneric<double>... etc. 我有一个类MyGeneric <T>,以及一些从类型MyGeneric <string>,MyGeneric <int>,MyGeneric <double> ...等创建的缓存数据。
Somewhere I have to check certain data to see if it is MyGeneric, I code like this: 我必须在某些地方检查某些数据以查看它是否是MyGeneric,我这样编码:
if (data is MyGeneric<>) { // can't compile
// ... do something
}
or 要么
if (data.GetType() == typeof(MyGeneric<>)
|| typeof(MyGeneric<>).isAssginableFrom(data.GetType())) {
// no exception but none of these comparison works
}
or this kind of stupid implemention works but i'd like to throw it away: 或这种愚蠢的实现工作,但我想扔掉它:
if (data.GetType().Name.StartsWith(typeof(MyGeneric<>).Name) { ... }
Is there a way to check relations between actual data type and open generic type (MyGeneric<>) ? 有没有一种方法可以检查实际数据类型和开放通用类型(MyGeneric <>)之间的关系?
What you call open generic type is known as generic type definition : 您所谓的开放通用类型称为通用类型定义 :
if(data.GetType().GetGenericTypeDefinition() == typeof(MyGeneric<>))
{
}
