我有一个.net 4.0控制台应用程序生成SQL并将其存储在一个字符串变量。我想这个字符串直接复制到剪贴板。到目前为止，所有我的研究表明，只有这样，这都不可能做的是通过添加引用System.Windows.Forms的。我不想一个引用到一个组件，它是无关的一个控制台应用程序。

I have a .NET 4.0 console app that generates SQL and stores it in a string variable. I want this string to be copied directly to the clipboard. So far, all my research indicates that the ONLY way this can possibly be done is by adding a reference to System.Windows.Forms. I do not want to add a reference to an assembly that is irrelevant to a console app.

内，其中我们当前存在的宇宙中，是有文本字符串复制到内一个控制台应用程序剪贴板，不涉及增加提及System.Windows.Forms的或任何其他组件，其目的是对公知的方法不相干的一个最基本的控制台应用程序？

Within the universe in which we currently exist, is there a known method of copying a string of text to the clipboard within a console app that does not involve adding a reference to System.Windows.Forms nor any other assembly whose purpose is irrelevant to a bare-bones console application?

推荐答案

平台调用剪贴板API的是一个可能的解决方案。例如：

Platform Invoking the Clipboard APIs is a possible solution. Example:

using System.Runtime.InteropServices;
class Program
{
    [DllImport("user32.dll")]
    internal static extern bool OpenClipboard(IntPtr hWndNewOwner);

    [DllImport("user32.dll")]
    internal static extern bool CloseClipboard();

    [DllImport("user32.dll")]
    internal static extern bool SetClipboardData(uint uFormat, IntPtr data);

    [STAThread]
    static void Main(string[] args)
    {
        OpenClipboard(IntPtr.Zero);
        var yourString = "Hello World!";
        var ptr = Marshal.StringToHGlobalUni(yourString);
        SetClipboardData(13, ptr);
        CloseClipboard();
        Marshal.FreeHGlobal(ptr);
    }
}

这仅仅是一个例子。加入少许错误处理周围的code，如检查P的返回值/启动功能将是一个很好的补充。

This is just an example. Adding a little error handling around the code, like checking the return values of the P/Invoke functions would be a good addition.

SetClipboardData是有趣的一点，你也想确保你打开和关闭剪贴板了。

SetClipboardData is the interesting bit, you also want to make sure you open and close the clipboard, too.

在 13 传递的第一个参数是数据格式。 13 意味着单code字符串

The 13 passed in as the first argument is the data format. 13 means unicode string.
