如何使用user32.dll获得特定窗口的句柄?

谁能给我一个简短的例子?

使用user32.dll获取特定窗口的句柄

尝试如下:

// For Windows Mobile, replace user32.dll with coredll.dll
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
// Find window by Caption only. Note you must pass IntPtr.Zero as the first parameter.
[DllImport("user32.dll", EntryPoint="FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);
// You can also call FindWindow(default(string), lpWindowName) or FindWindow((string)null, lpWindowName)

你可以像下面这样使用这些声明

// Find window by Caption
public static IntPtr FindWindow(string windowName)
{
    var hWnd = FindWindow(windowName, null); 
    return hWnd;
}

下面是代码的简洁版本:

public class WindowFinder
{
    // For Windows Mobile, replace user32.dll with coredll.dll
    [DllImport("user32.dll", SetLastError = true)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    
    public static IntPtr FindWindow(string caption)
    {
        return FindWindow(String.Empty, caption);
    }
}
