1.string转int ：int id = int.Parse(str);

2.int转string：string str = id.ToString();

3.判断两字符串是否相等：str1.Equals(str2)或者String.Equals(str1,str2);

using (StreamReader reader = new StreamReader(mpath))
{
string lineStr;
int row = 0;
for (int lineIdx = 1; (lineStr = reader.ReadLine()) != null; lineIdx++)
{
row++;
}
}5.写文件：
