File Create string  returns an instance of the FileStream class  You can call the Stream Close   method on this object in order to close it and release resources that it s using     var myFile   File Create myPath   myFile Close      However  since FileStream implements IDisposable  you can take advantage of the using statement  generally the preferred way of handling a situation like this   This will ensure that the stream is closed and disposed of properly when you re done with it   using  var myFile   File Create myPath           interact with myFile here  it will be disposed automatically

The reason is because a FileStream is returned from your method to create a file  You should return the FileStream into a variable or call the close method directly from it after the File Create    It is a best practice to let the using block help you implement the IDispose pattern for a task like this  Perhaps what might work better would be   if  File Exists myPath       using FileStream fs   File Create myPath      using StreamWriter writer   new StreamWriter fs             do your work here
