C＃与此代码混淆 [英] C# confusion with this code

问题描述

这是我的代码

this is my code

//part of the idle stuff
        [StructLayout(LayoutKind.Sequential)]
        struct LASTINPUTINFO
        {
            public static readonly int SizeOf = Marshal.SizeOf(typeof(LASTINPUTINFO));

            [MarshalAs(UnmanagedType.U4)]
            public UInt32 cbSize;
            [MarshalAs(UnmanagedType.U4)]
            public UInt32 dwTime;
        }

uint idleTime = 0;
            LASTINPUTINFO lastInputInfo = new LASTINPUTINFO();

            //int y = Convert.ToInt32(lastInputInfo);
            uint y = Convert.ToUInt32(lastInputInfo);
            lastInputInfo.cbSize = Marshal.SizeOf(y);
            lastInputInfo.dwTime = 0;</pre>

i顺便使用这两种方法，因为它无法弥补它的意思，这是我的错误





< code>错误1无法将类型'int'隐式转换为'uint'。存在显式转换（您是否缺少演员表？）Z：\ UnHidden\UnHidden\Form1.cs 48 36 UnHidden< / code>



和i每个转换代码得到相同的错误，有人可以告诉我发生了什么以及如何解决这个问题？

i used both those methods by the way because it can't make up its mind and this is my error


<code>Error 1 Cannot implicitly convert type 'int' to 'uint'. An explicit conversion exists (are you missing a cast?) Z:\UnHidden\UnHidden\Form1.cs 48 36 UnHidden</code>

and i get the same error with each of those convert codes, can some one please tell me whats happening and how i can possibly fix this?

推荐答案

错误非常明显，并告诉你该怎么做：要么将定义更改为Int32，要么将值转换为UInt32：

The error is pretty explicit, and does tell you what to do: either change the definition to Int32, or cast the values to UInt32:

lastInputInfo.cbSize = (UInt32) Marshal.SizeOf(y);
