using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace _297 { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { using (FileStream fs=new FileStream(Server.MapPath("Text1.txt"),FileMode.Open,FileAccess.Read)) { StreamReader sr = new StreamReader(fs, true); char[] bufferChar = new char[10]; sr.Read(bufferChar, 5, 5); foreach(char c in bufferChar) { Response.Write(c); } } } } }
sr.Read(bufferChar, 5, 5); 此方法的构造函数是sr.read(char[] buffer,int index,int count),index是指buffer缓存的起始位置,并不是sr中字符的位置。
