答
它是 泛型类型参数.它也可以是其他东西,例如:
It's a symbol for a generic type parameter. It could just as well be something else, for example:
public class SomeBase<GenericThingy> where GenericThingy : SomeBase<GenericThingy>, new()
只有 T 是 Microsoft 使用和鼓励的默认值.
Only T is the default one used and encouraged by Microsoft.
