How to: Create a Data Object
The following examples show various ways to create a data object using the constructors provided by the xref:System.Windows.DataObject class.
Example
Description
The following example code creates a new data object and uses one of the overloaded constructors (xref:System.Windows.DataObject.%23ctor%28System.Object%29) to initialize the data object with a string. In this case, an appropriate data format is determined automatically according to the stored data's type, and auto-converting of the stored data is allowed by default.

Example
Description
The following example code creates a new data object and uses one of the overloaded constructors (xref:System.Windows.DataObject.%23ctor%28System.String%2CSystem.Object%29) to initialize the data object with a string and a specified data format. In this case the data format is specified by a string; the xref:System.Windows.DataFormats class provides a set of pre-defined type strings. Auto-converting of the stored data is allowed by default.

Example
Description
The following example code creates a new data object and uses one of the overloaded constructors (xref:System.Windows.DataObject.%23ctor%2A) to initialize the data object with a string and a specified data format. In this case the data format is specified by a xref:System.Type parameter. Auto-converting of the stored data is allowed by default.

Example
Description
The following example code creates a new data object and uses one of the overloaded constructors (xref:System.Windows.DataObject.%23ctor%28System.String%2CSystem.Object%2CSystem.Boolean%29) to initialize the data object with a string and a specified data format. In this case the data format is specified by a string; the xref:System.Windows.DataFormats class provides a set of pre-defined type strings. This particular constructor overload enables the caller to specify whether auto-converting is allowed.
