如何在带有c#的DllImport上获得剪贴板文本？
如何在带有c#的DllImport上获得剪贴板文本？
提问于 2018-08-18 21:24:25
下面的代码在OSX上设置剪贴板文本。什么等同于阅读剪贴板文本？
static class OsxClipboard
{
public static void SetText(string text)
{
var nsString = objc_getClass("NSString");
var str = objc_msgSend(objc_msgSend(nsString, sel_registerName("alloc")), sel_registerName("initWithUTF8String:"), text);
var dataType = objc_msgSend(objc_msgSend(nsString, sel_registerName("alloc")), sel_registerName("initWithUTF8String:"), NSPasteboardTypeString);
var nsPasteboard = objc_getClass("NSPasteboard");
var generalPasteboard = objc_msgSend(nsPasteboard, sel_registerName("generalPasteboard"));
objc_msgSend(generalPasteboard, sel_registerName("clearContents"));
objc_msgSend(generalPasteboard, sel_registerName("setString:forType:"), str, dataType);
objc_msgSend(str, sel_registerName("release"));
objc_msgSend(dataType, sel_registerName("release"));
}
[DllImport("/System/Library/Frameworks/AppKit.framework/AppKit")]
static extern IntPtr objc_getClass(string className);
[DllImport("/System/Library/Frameworks/AppKit.framework/AppKit")]
static extern IntPtr objc_msgSend(IntPtr receiver, IntPtr selector);
[DllImport("/System/Library/Frameworks/AppKit.framework/AppKit")]
static extern IntPtr objc_msgSend(IntPtr receiver, IntPtr selector, string arg1);
[DllImport("/System/Library/Frameworks/AppKit.framework/AppKit")]
static extern IntPtr objc_msgSend(IntPtr receiver, IntPtr selector, IntPtr arg1, IntPtr arg2);
[DllImport("/System/Library/Frameworks/AppKit.framework/AppKit")]
static extern IntPtr sel_registerName(string selectorName);
const string NSPasteboardTypeString = "public.utf8-plain-text";

要从剪贴板获取数据，您需要添加对Windows的引用。下面也是如此
1)项目:添加引用: Net : PresentationCore
2)项目:添加引用: Net : WindowBase
3)添加到模块顶部:使用System.Windows；
4)然后在代码中使用剪贴板方法之一，如Clipboard.GetText()；
