IDataObject.GetData Method (Type)


Retrieves the data associated with the specified class type format.

Namespace:   System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

object GetData(
	Type format


Type: System.Type

A Type representing the format of the data to retrieve. See DataFormats for predefined formats.

Return Value

Type: System.Object

The data associated with the specified format, or null.

If this method cannot find data in the specified format, it attempts to convert the data to the format. If the data cannot be converted to the specified format, this method returns null.

To determine whether data is associated with, or can be converted to, a format, call GetDataPresent before calling GetData. Call GetFormats for a list of valid formats for the data stored in this instance.


Data can be converted to another format if it was stored specifying that conversion is allowed, and if the requested format is compatible with the stored format. For example, data stored as Unicode can be converted to text.

For an implementation of this method, see DataObject.GetData.

This example uses the DataObject class, which implements IDataObject, to demonstrate the use of the GetData method. The method is used to retrieve the data stored in myObject, which is associated with a specific type, myType. The type of the retrieved data is displayed in a message box. The example assumes that you have already created a Form named Form1.

private void GetData2() 
    // Creates a component.
    Component myComponent = new Component();

    // Creates a data object, and assigns it the component.
    DataObject myDataObject = new DataObject(myComponent);

    // Creates a type, myType, to store the type of data.
    Type myType = myComponent.GetType();

    // Retrieves the data using myType to represent its type.
    Object myObject = myDataObject.GetData(myType);
    if(myObject != null)
        MessageBox.Show("The data type stored in the data object is " +
            myObject.GetType().Name + ".");
        MessageBox.Show("Data of the specified type was not stored " +
            "in the data object.");
