封装好的类库vs插件

[DllImport("user32.dll")]
public static extern int SetCursorPos(int x, int y);

 

[DllImport("user32.dll", EntryPoint="GetWindowText")]
public static extern int GetWindowText (
int hwnd,
string lpString,
int cch
);     
调用:     
StringBuilder s = new StringBuilder(512);                              
int i = GetWindowText(this.Handle, s, s.Capacity);                
MessageBox.Show(s.ToString());
