Fields
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. |
GenerateUniqueName | 0 | Automatically append a number to the base of the specified name if the file or folder already exists. For example, if |
OpenIfExists | 3 | Return the existing item if the file or folder already exists. |
ReplaceExisting | 1 | Replace 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.
