# 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.

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.

|
|
### 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.
