C#点击load读取数据库数据现需要同时在指定位置创建TXT文件，并把读取的内容生成到TXT文件内部

详细如下



这是获取的数据把第一个的B39000-T4061-P810-S09中的P8改成BC，并在前面添加一些东西这是txt结果图。

这是部分代码
namespace LDD__Generator
{
public partial class LDD : Form
{
public LDD()
{
InitializeComponent();
}

    private void button1_Click(object sender, EventArgs e)
    {
        GetData();

    }

    private void GetData()
    {
        try
        {
            DataTable dtMAT_NR = SQLUtility.Select("Select MAT_NR From ADE_LOS Where LOS_NR = '" + txtLOS_NR.Text.Trim() + "'", null);

            DataTable dtPANELID = SQLUtility.Select("Select PANELID From FCBDB.dbo.PANELTAB Where LOSID ='" + txtLOS_NR.Text.Trim() + "'", null);

        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            return;
        }
    }

    private void txtLOS_NR_KeyPress(object sender, KeyPressEventArgs e)
    {
        GetData();
    }

}

}

你循环table，用streamwriter写就行了

         private void GetData()
        {
            try
            {
                DataTable dtMAT_NR = SQLUtility.Select("Select MAT_NR From ADE_LOS Where LOS_NR = '" + txtLOS_NR.Text.Trim() + "'", null);

                DataTable dtPANELID = SQLUtility.Select("Select PANELID From FCBDB.dbo.PANELTAB Where LOSID ='" + txtLOS_NR.Text.Trim() + "'", null);

                //遍历2个表格组合好字符串调用IO写入记事本不就好了
                string s="";
                foreach (DataRow dr in dtMAT_NR) s += "MAT_NR=" + dr[0].ToString() + "\r\n";
                foreach (DataRow dr in dtPANELID) s += "PAN=" + dr[0].ToString() + "\r\n";
                //记得修改第一个参数为你需要制定的位置
                System.IO.File.WriteAllText(@"c:\xxx.txt",s,System.Text.Encoding.UTF8);

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
                return;
            }
        }
