Use Clipboard.SetText to copy text and Clipboard.GetText to paste after checking Clipboard.ContainsText. You can specify formats like UnicodeText, Rtf, or Html via the TextDataFormat parameter.

Call Clipboard.SetImage with a BitmapSource, and retrieve it with Clipboard.GetImage after checking Clipboard.ContainsImage. To copy a UI element, render it into a RenderTargetBitmap first, then pass that bitmap to SetImage.

Create a DataObject, register a custom format name with DataFormats.GetDataFormat, and call SetData with that format before Clipboard.SetDataObject. The receiving app checks GetDataPresent for the same format name and retrieves the object with GetData.

The clipboard is a shared system resource and throws ExternalException when locked by another process. Wrap calls in try-catch and retry with a short delay, as shown in the TrySetTextWithRetry pattern.

Register the window handle with the Win32 AddClipboardFormatListener API and hook WndProc via HwndSource to receive WM_CLIPBOARDUPDATE messages. Remove the listener and hook when the window closes.

Only if you call Clipboard.SetDataObject with the copy parameter set to true. With the default false value, the data is removed from the clipboard when the application exits.
