C # IO Read-write file Method encapsulation

Code Listing 1:

        /// <summary>        ///function: FileStream file stream Read file/// </summary>        /// <param name= "FilePath" >Parameters: File path</param>        /// <returns>return Value: StreamReader object</returns>         Public StaticStreamReader READFILEBYFS (stringFilePath) {FileStream Fs=NULL; StreamReader Sr=NULL; Try{Fs=NewFileStream (FilePath, FileMode.OpenOrCreate, FileAccess.Read); Sr=NewStreamReader (Fs, Encoding.default); }            Catch(IOException e) {Throwe; }            returnSr; }

Code Listing 2:

       /// <summary>        ///function: FileStream file stream Write file/// </summary>        /// <param name= "FilePath" >Parameters: File path</param>        /// <returns>return Value: StreamWriter object</returns>         Public StaticStreamWriter WRITEFILEBYFS (stringFilePath) {FileStream Fs=NULL; StreamWriter Sw=NULL; Try{Fs=NewFileStream (FilePath, FileMode.OpenOrCreate, FileAccess.Write); Sw=NewStreamWriter (Fs, Encoding.default); }            Catch(IOException e) {Throwe; }            returnSw; }

Call these two methods to read and write the file call method I will not write
