C# IO读写文件方法封装代码 1：
/// <summary> /// 功能：FileStream文件流读取文件 /// </summary> /// <param name="filePath">参数：文件路径</param> /// <returns>返回值：StreamReader对象</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; }
代码 2：
/// <summary> /// 功能：FileStream文件流写文件 /// </summary> /// <param name="filePath">参数：文件路径</param> /// <returns>返回值：StreamWriter对象</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; }
调用这两个方法读写文件的调用方式我就不写了
