读操作:
方法1:
string str = File.ReadAllText(@filepath, Encoding.Default);
方法2:
byte[] buffer = File.ReadAllBytes(@filepath);string str = Encoding.Default.GetString(buffer);
方法3:
string[] buffer = File.ReadAllLines(@filepath,Encoding.Default);string str = "" ;foreach (var buf in buffer){ str = str + buf +"/n";}
方法4:
FileStream fsRead = new FileStream(@filepath, FileMode.OpenOrCreate);byte[] buffer = new byte[1024 * 1024 * 5];int length = fsRead.Read(buffer, 0, buffer.Length);string str = Encoding.Default.GetString(buffer, 0, length);fsRead.Close();fsRead.Dispose();
方法5:
string str ="";using (FileStream fsRead = new FileStream(@filepath, FileMode.OpenOrCreate,Fileaccess.Read)){ byte[] buffer = new byte[1024 * 1024 * 5]; int length = fsRead.Read(buffer, 0, buffer.Length); str = Encoding.Default.GetString(buffer, 0, length);}
写操作:
方法1:
File.WriteAllText(@filepath, str, Encoding.Default);
方法2:
byte[] buffer = Encoding.Default.GetBytes(str);File.WriteAllBytes(@filepath,buffer);
方法3:
File.WriteAllLines(@filepath, str.Split(' '),Encoding.Default);
方法4:
FileStream fsWrite = new FileStream(@filepath, FileMode.OpenOrCreate, FileAccess.Write);byte[] buffer = Encoding.Default.GetBytes(str);fsWrite.Write(buffer, 0, buffer.Length);fsWrite.Close();fsWrite.Dispose();
方法5:
byte[] buffer = Encoding.Default.GetBytes(str);using (FileStream fsWrite = new FileStream(@filepath, FileMode.OpenOrCreate, FileAccess.Write)){ fsWrite.Write(buffer, 0, buffer.Length);}
