Save or append text to a file (c#)

偶然看到rippleyong [涟漪勇]Post了一个VB.NET版的Save or append text to a file,于是一阵手痒，便有了这C#版的Method：

public static bool SaveTextToFile(string filepath,string text,bool append)
    {    
        using(System.IO.StreamWriter sw=new System.IO.StreamWriter(filepath,append))
        {
            try
            {        
                sw.Write(text);
                return true;
            }
            catch
            {
                return false;
            }
        }        
    }
