Following function will get the clipboard data:
[DllImport("user32.dll")]
static extern IntPtr GetClipboardData(uint uFormat);
[DllImport("user32.dll")]
static extern bool IsClipboardFormatAvailable(uint format);
[DllImport("user32.dll", SetLastError = true)]
static extern bool OpenClipboard(IntPtr hWndNewOwner);
[DllImport("user32.dll", SetLastError = true)]
static extern bool CloseClipboard();
[DllImport("kernel32.dll")]
static extern IntPtr GlobalLock(IntPtr hMem);
[DllImport("kernel32.dll")]
static extern bool GlobalUnlock(IntPtr hMem);
const uint CF_UNICODETEXT = 13;
public static string GetText()
{
if (!IsClipboardFormatAvailable(CF_UNICODETEXT))
return null;
if (!OpenClipboard(IntPtr.Zero))
return null;
string data = null;
var hGlobal = GetClipboardData(CF_UNICODETEXT);
if (hGlobal != IntPtr.Zero)
{
var lpwcstr = GlobalLock(hGlobal);
if (lpwcstr != IntPtr.Zero)
{
data = Marshal.PtrToStringUni(lpwcstr);
GlobalUnlock(lpwcstr);
}
}
CloseClipboard();
return data;
}
In order to get the size of clipboard text, you would need to copy the text in a file and then get the size of file as shown in the below code:
public long getClipboardTextSize()
{
string text = GetText();
System.IO.File.WriteAllText("C:\\ClipboardText.txt", text);
FileInfo fi = new FileInfo(path);
if (fi.Exists)
{
return fi.Length;
}
else
{
return 0;
}
}
}

static extern IntPtr GetClipboardData(uint uFormat);

const uint CF_UNICODETEXT = 13;

{

{
var lpwcstr = GlobalLock(hGlobal);

{
data = Marshal.PtrToStringUni(lpwcstr);
GlobalUnlock(lpwcstr);
}
}
CloseClipboard();
return data;

Great post! The example for getting clipboard data switch free game and its size is really helpful. Simple, clear, and practical for quick implementation. Thanks for sharing this useful coding tip.
