如何判断对象内部是否存在sbyte类型？

Question

void Do() {
   object obj = func();
   bool isSByte = obj.GetType() is sbyte; //not correct
}
object func() {
   object obj = new sbyte(-124);
   return obj;
}

Answer 1

是（此变体更可取）

bool isSByte = obj is sbyte;

获取类型

bool isSByte = obj.GetType() == typeof(sbyte);

检查继承：

// sbyte
bool isInherits = typeof(sbyte).IsAssignableFrom(obj.GetType()); // true

// for classes
bool isMemoryStreamInheritsStream = typeof(Stream).IsAssignableFrom(typeof(MemoryStream));  // true (MemoryStream based on Stream)
