Var fileStream=File. OpenWrite (" path "); 

//set to the location of the current flow 
FileStream. Seek (100, SeekOrigin. Current); 

//to write data flow 
Byte [] data=https://bbs.csdn.net/topics/Encoding.UTF8.GetBytes (" hello word!" ); 
FileStream. Write (data, 0, the data Length); 

//the data read from the stream, the count for the number of actual read 
Int count=0; 
Byte [] buff=new byte [1024]. 
If ((count=fileStream. Read (buff, 0, buff. Length)) & gt; 0)
