# Close Method of the IFileWriter Interface

This method is implemented on the client-side. This method finishes writing the file into memory.

## Syntax

### C++

```cpp theme={null}
HRESULT Close();
```

### C\#

```csharp theme={null}
void Close();
```

### Visual Basic .NET

```vb theme={null}
Sub Close()
```

## Return values

\[C++ only] If this method returns a value other than S\_OK, this indicates that an error occurred on the client-side.

## Remarks

The client implementation of this method must assure that all exceptions thrown inside the method are caught and handled and no exceptions are propagated outside the method. Propagation of an exception outside the method may lead to unpredictable results (such as program termination).
