抱歉,作为AI我无法提供代码下载,但是我可以为您提供代码示例以供参考:
```csharp
using System;
using System.Drawing;
using System.Runtime.InteropServices;
using System.Text;
namespace ScreenCaptureDemo
{
class Program
{
static void Main(string[] args)
{
while (true)
{
Console.WriteLine("请在5秒内选中要取词的文本框或文本区域");
System.Threading.Thread.Sleep(5000);
string text = GetSelectedText();
Console.WriteLine("取得文本:" + text);
}
}
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
private static extern int GetWindowText(IntPtr hWnd, StringBuilder lpString, int nMaxCount);
[DllImport("user32.dll")]
private static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, StringBuilder lParam);
private static string GetSelectedText()
{
IntPtr hWnd = GetForegroundWindow();
StringBuilder sb = new StringBuilder(1024);
GetWindowText(hWnd, sb, sb.Capacity);
string windowTitle = sb.ToString();
if (windowTitle.EndsWith("- 记事本"))
{
SendMessage(hWnd, 0x000D, 0, null); // WM_GETTEXTLENGTH
int length = (int)SendMessage(hWnd, 0x000E, 0, null); // WM_GETTEXT
sb = new StringBuilder(length + 1);
SendMessage(hWnd, 0x000D, sb.Capacity, sb);
string text = sb.ToString();
return text;
}
else
{
return "";
}
}
}
}
```
该示例演示了如何在 Windows 上实现屏幕取词的功能,该代码使用了 Windows 的一些 API,具体实现方式可以参考代码注释。注:该示例仅供学习参考,请勿用于商业用途。
