Convert.ChangeType matrix

Question

Is there any resource that shows .NET Convert.ChangeType() results in a table? ie converting from which type to which type will be successful, overflow, invalid cast or throwing other exceptions.

In particular, I want to know whether converting between signed and unsigned numerals of the same size (eg Int32 and UInt32) will be successful, overflow or invalid cast.

Answer 1

int32的最大值为2,147,483,647，UInt32的最大值为4,294,967,295，因此，如果将数字从int32转换为uint32并停留在int32的最大边界上，反之亦然，那么就不会有问题，否则它将给您一个被零除的异常
