jiezhi(風依舊) :
我是想用 GetWindowText
不知道该怎么套，您能给个代码吗？

[jiezhi]

public class Win32API {
[DllImport("User32.Dll")]
public static extern void GetWindowText(int h, StringBuilder s,
int nMaxCount);
}
public class Window {
internal int h; // Internal handle to Window.
public String GetText() {
StringBuilder sb = new StringBuilder(256);
Win32API.GetWindowText(h, sb, sb.Capacity + 1);
return sb.ToString();
}
}
