具體不做詳細介紹了，直接上代碼
/// <summary> /// 功能：FileStream文件流讀取文件 /// </summary> /// <param name="filePath">參數：文件路徑</param> /// <returns>返回值：StreamReader對象</returns> public static StreamReader ReadFileByFs(string filePath) { FileStream Fs = null; StreamReader Sr = null; try { Fs = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Read); Sr = new StreamReader(Fs, Encoding.Default); } catch (IOException e) { throw e; } return Sr; } 代碼 2：
/// <summary> /// 功能：FileStream文件流寫文件 /// </summary> /// <param name="filePath">參數：文件路徑</param> /// <returns>返回值：StreamWriter對象</returns> public static StreamWriter WriteFileByFs(string filePath) { FileStream Fs = null; StreamWriter Sw = null; try { Fs = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write); Sw = new StreamWriter(Fs, Encoding.Default); } catch (IOException e) { throw e; } return Sw; }以上代碼針對IO讀寫文件方法封裝做了詳細介紹，希望能夠幫助到大家。
