C#点击load在指定位置创建TXT文件，并把读取的内容生成到TXT文件（已实现读取数据库内容）

问题描述：

代码如下，求帮忙
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();
}

}

这个是需要的结果图

求指教怎么写

答

         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;
            }
        }

就是两个操作，说白了就是一个文件操作问题。File之类的，你看下

答

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);

            string s = "";
            foreach (DataRow dr in dtMAT_NR.Rows)
            {
                s += "MAT_NR=" + dr[0].ToString() + "\r\n";
            }
            foreach (DataRow dr in dtPANELID.Rows)
            {
                s += "PAN=" + dr[0].ToString() + "\r\n";
            }
            System.IO.File.WriteAllText(@"D:\A.txt", s, System.Text.Encoding.UTF8);

        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message.ToString(), "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
            return;
        }
    }
            根据大神答案进行一些细节修改已经能完成运行，留给需要的人看看
