CreationCollisionOption Enum

Definition

Namespace:

Windows.Storage

Specifies what to do if a file or folder with the specified name already exists in the current folder when you create a new file or folder.

public enum class CreationCollisionOption

/// [Windows.Foundation.Metadata.ContractVersion(Windows.Foundation.UniversalApiContract, 65536)]
enum class CreationCollisionOption

[Windows.Foundation.Metadata.ContractVersion(typeof(Windows.Foundation.UniversalApiContract), 65536)]
public enum CreationCollisionOption

var value = Windows.Storage.CreationCollisionOption.generateUniqueName

Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Fields

Name	Value	Description
GenerateUniqueName	0	Automatically append a number to the base of the specified name if the file or folder already exists. For example, if MyFile.txt already exists, then the new file is named MyFile (2).txt. If MyFolder already exists, then the new folder is named MyFolder (2).
ReplaceExisting	1	Replace the existing item if the file or folder already exists.
FailIfExists	2	Raise an exception of type System.Exception if the file or folder already exists. Methods that don't explicitly pass a value from the CreationCollisionOption enumeration use the FailIfExists value as the default when you try to create, rename, copy, or move a file or folder.
OpenIfExists	3	Return the existing item if the file or folder already exists.

Remarks

Methods that don't explicitly pass a value from the CreationCollisionOption enumeration use the FailIfExists value as the default when you create a file or folder.

For example, the CreateFileAsync method has one overload, CreateFileAsync (String, .CreationCollisionOption), that explicitly passes a value from the CreationCollisionOption enumeration. If you call the other overload, CreateFileAsync (String), the method uses the FailIfExists option as the default.
