Guide on how to create generic Clipboard manager in C#. Implement Copy Paste C# code, download the full source code.


It is easy to implement Copy Paste operations using C# code.

First, you need to make the class that you want to put into clipboard- serializable.

    public class ClipBoardTestCase
        public ClipBoardTestCase(List<TestCase> testCases, ClipBoardCommand clipBoardCommand)
            this.TestCases = testCases;
            this.ClipBoardCommand = clipBoardCommand;

        public List<TestCase> TestCases { get; set; }

        public ClipBoardCommand ClipBoardCommand { get; set; }

ClipBoardCommand is a simple enum with three values: Copy, Cut, None. We are going to use it later in the paste operation to determine if the clip should be removed from the clipboard.

Also, make sure that your class is serializable, add the [Serializable] attribute to it. If you are working with system objects, be sure that all of them can be serialized. I have noticed that some of the core TFS objects are not. If that is the case, just add a [NonSerialized] attribute to them.

Serialization Tester

Also, you can use the following method to test if the properties and variables of your class can be serialized.

public static bool IsSerializable(object obj)
    MemoryStream mem = new MemoryStream();
    BinaryFormatter bin = new BinaryFormatter();
        bin.Serialize(mem, obj);
        return true;
    catch (Exception ex)
        MessageBox.Show("Your object cannot be serialized." +
                         " The reason is: " + ex.ToString());
        return false;

Implement Copy Paste C# Serialization Manager

I have created a reusable generic class for the basic clipboard actions; you can use it directly.

public class ClipBoardManager<T> where T : class
        public static T GetFromClipboard()
            T retrievedObj = null;
            IDataObject dataObj = Clipboard.GetDataObject();            
            string format = typeof(T).FullName;
            if (dataObj.GetDataPresent(format))
                retrievedObj = dataObj.GetData(format) as T;                
            return retrievedObj;

        public static void CopyToClipboard(T objectToCopy)
            // register my custom data format with Windows or get it if it's already registered
            DataFormats.Format format = DataFormats.GetFormat(typeof(T).FullName);

            // now copy to clipboard
            IDataObject dataObj = new DataObject();
            dataObj.SetData(format.Name, false, objectToCopy);
            Clipboard.SetDataObject(dataObj, false);

        public static void Clear()

The usage is simple. Just initialize your object and pass it to the manager's method.

ClipBoardCommand clipBoardCommand = isCopy ? ClipBoardCommand.Copy : ClipBoardCommand.Cut;
ClipBoardTestCase clipBoardTestCase = new ClipBoardTestCase(testCases, clipBoardCommand);

When you are performing cut operations, you need to remove the last clip from the clipboard or clear it all. So you can use the ClipBoardCommand enum to do it.

Task t = Task.Factory.StartNew(() =>
                TestSuiteManager.PasteTestCasesToSuite(suiteToPasteIn.Id, clipBoardTestCase);
            t.ContinueWith(antecedent =>
                if (clipBoardTestCase.ClipBoardCommand.Equals(ClipBoardCommand.Cut))
            }, TaskScheduler.FromCurrentSynchronizationContext());

If you need to add more logic to your clipboard manager, you can visit the official MSDN documentation here.
