C#编程 如何统计txt或者word文档中某个字出现的次数，求大神指导，稍微具体点，谢谢

Answer 1

假如是xp系统下桌面的a.txt文档，那么：
try
{
String path = "C:\\Documents and Settings\\Administrator\\桌面\\a.txt";
StreamReader sr = new StreamReader(path);
String line;//接收字节流
String str = "";//接收txt文档内容的变量
while ((line = sr.ReadLine()) != null)
{
str += line;
}
}
catch (Exception e)
{
Console.WriteLine(e.Message);
}

int count = 0;//计数器
string search = "的"; //要查的字符串
for (int i = 0; i < str.Length-search.Length; i++)
{
if (str.Substring(i, search.Length) == search)
{
count++;
}
}
Console.WriteLine("在a.txt中，“的”出现了"+ count +"次。");
