Meaning of 1U in C# and OPEN XML SDK 2.0

Question

I always see the 1U code in C# especially in styles in OPEN XML SDK 2.0. Does anybody know the meaning of it?

Answer 1

U表示数字是无符号常量。

Answer 2

It's an unsigned literal .

For example, if you do:

var u = 1U;
Console.Write(u.GetType());

It'll tell you that it's a System.UInt32 .

See the C# spec for details.

Answer 3

它指定您具有值为1的unsigned int 。
