读写TXT文档

实践中经常用到读写txt文件的时候，里面下面两个函数即可实现读写，filePath为txt文件的绝对路径

/// <summary>
/// 写txt文件
/// </summary>
/// <param name="filePath">txt文件路径</param>
private void WriteFile(string filePath)
{
    StreamWriter write = new StreamWriter(filePath);
    string line = "";
    write.WriteLine(line);//写第一行
    write.Close();//关闭写
}

/// <summary>
/// 读txt文件
/// </summary>
/// <param name="filePath">txt文件路径</param>
private void ReadFile(string filePath)
{
    StreamReader read = new StreamReader(filePath);
    string line = string.Empty;
    line = read.ReadLine();//读第一行
    read.Close();//关闭读
}
