Question

求asp.net用c#语言编写获取统计文件.txt的里面的字数

Answer 1

1.先读取文件
2.统计

/// <summary>
/// 文件的读取
/// </summary>
/// <param name="path">文件地址</param>
/// <returns></returns>
public string fileReaders(string path)
{
FileStream fs = File.Open(path, FileMode.Open);
StreamReader sr = new StreamReader(fs, Encoding.Default);
StringBuilder con = new StringBuilder();
do
{
con.Append(sr.ReadLine());
} while (sr.Peek() > -1);
fs.Close();
fs.Dispose();
sr.Close();
sr.Dispose();
return con.ToString();
}

///前台调用
string str=fileReaders(文件地址);
long length=(long)str.Length;

追问

protected void Page_Load(object sender, EventArgs e)
{
string strLine = "";
int i = 0;
{
StreamReader sr = new StreamReader(Server .MapPath ("mytext.txt"));
strLine = sr.ReadLine();
while (strLine != null)
{
Response.Write(strLine + "");
strLine = sr.ReadLine();
i++;
}
Response.Write(i);
sr.Dispose();
sr.Close();
}
}
能帮我把这段计算行数的代码实现有统计字数的功能吗 谢谢

protected void Page_Load(object sender, EventArgs e)
{
long length=0;
string strLine = "";
int i = 0;
{
StreamReader sr = new StreamReader(Server .MapPath ("mytext.txt"));
strLine = sr.ReadLine();
length=strLine.Length;
while (strLine != null)
{
Response.Write(strLine + "");
strLine = sr.ReadLine();
length+=strLine.Length;
}
Response.Write(length);
sr.Dispose();
sr.Close();
}
}
附：如果你想学好这项语言，就要学会将功能模块进行分类，比如你贴出来的这段代码，写的太死，代码的复用就失去了它的色彩，所以，为了以后不用再大量的重新编写代码，你最好将代码写进类库，将代码功能进行分类，这样便于以后写项目，最经典的例子就是将程序进行分层，你可以上网进行查解一下，还有内存，有事就不再说了……
如果你想学好这门语言，就必须考虑它的分层，分是分离，层是层次，一定要记住这就句话。

追问

length+=strLine.Length;
这段代码出了问题，错误显示是：“未将对象引用设置到对象的实例。”我还是非常菜的菜鸟 改不来 还是得麻烦你帮忙下 谢谢

long length = 0;
string strLine = "";
int i = 0;
{
StreamReader sr = new StreamReader(Server .MapPath ("mytext.txt"));
strLine = sr.ReadLine();
while (strLine != null)
{
Response.Write(strLine + "");
length += strLine.Length;
strLine = sr.ReadLine();
}
Response.Write(length);
sr.Dispose();
sr.Close();
}
