【整理】C# WinFrom 中如何txt内容与dataGridView互动
题目: txt内容为固定格式:帐号----密码----备注(用4个“-”分隔)
TXT内容如下:
baidu----123456----百度帐号
hao123----123456----hao123帐号
duowan----123456----多玩帐号
要求显示在dataGridView效果如下表格
帐号 密码 备注
baidu 123456 baidu帐号
hao123 123456 hao123帐号
duowan 123456 多玩帐号

private void button15_Click(object sender, EventArgs e)
{
//新建一个datatable用于保存读入的数据
DataTable dt = new DataTable();
//给datatable添加三个列
dt.Columns.Add("帐号", typeof(String));
dt.Columns.Add("密码", typeof(String));
dt.Columns.Add("备注", typeof(String));
//读入文件
StreamReader reader = new StreamReader(@"11\11.txt", Encoding.Default);
//循环读取所有行
while (!reader.EndOfStream)
{
//将每行数据,用-分割成3段
string[] data = reader.ReadLine().Replace("----", "-").Split('-');
//新建一行,并将读出的数据分段,分别存入3个对应的列中
DataRow dr = dt.NewRow();
dr[0] = data[0];
dr[1] = data[1];
dr[2] = data[2];
//将这行数据加入到datatable中
dt.Rows.Add(dr);
}
//将datatable绑定到datagridview上显示结果
dataGridView2.DataSource = dt;
}
