Using to Try/Finally

• Aug 09, 2018

Converts a using statement to a try/finally block.

Availability

Available from the context menu or via shortcuts:

• when the caret is on a using statement.

Notes

• The using statement is replaced with a variable initialization.
• The body of the using block is moved into the try block
• The finally block contains variable disposal code.

Example

C#

│using (FileStream lFS = new FileStream("", FileMode.CreateNew))
{
    lFS.SetLength(100);
    lFS.Flush();
    lFS.Close();
}

VB.NET

Dim lFS As FileStream = New FileStream("", FileMode.Create)
│Using lFS
    lFS.SetLength(100)
    lFS.Flush()
    lFS.Close()
End Using

Result:

C#

│FileStream lFS = new FileStream("", FileMode.CreateNew);
try
{
    lFS.SetLength(100);
    lFS.Flush();
    lFS.Close();
}
finally
{
    if (lFS != null)
        lFS.Dispose();
}

VB.NET

Dim lFS As FileStream = New FileStream("", FileMode.Create)
│Try
    lFS.SetLength(100)
    lFS.Flush()
    lFS.Close()
Finally
    If lFS IsNot Nothing Then
        lFS.Dispose()
    End If
End Try
