问题描述

if (dlgSave.ShowDialog() == DialogResult.OK)
            {

                //create the new file using the name of save dialog box
                FileStream fleProduction = new FileStream(dlgSave.FileName, FileMode.Create, FileAccess.Write, FileShare.Write);
                BinaryWriter bnrProduction = new BinaryWriter(fleProduction);

                //write each value in the file
                bnrProduction.Write(textBox1.Text);
                bnrProduction.Write(label1.Text);
}

//for load file
private void openToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (dlgOpen.ShowDialog() == DialogResult.OK)
            {
                FileStream fleProduction = new FileStream(this.dlgOpen.FileName, FileMode.Open, FileAccess.Read, FileShare.Read);
                BinaryReader bnrProduction = new BinaryReader(fleProduction);
               

                textBox1.Text = bnrProduction.ReadString();
                label1.Text = bnrProduction.ReadString();
}

推荐答案

要填充Datagrid，您需要将其与任何数据集或数据表连接。



要从Gridview加载或保存数据，它很容易保存文件格式为XML或JSON格式。



您也可以使用数据集直接导出为XML格式。



您可以浏览Gridview来制作自定义数据表或数据集..



如果您不需要创建数据表或数据集，那么可以通过网格中的每一行，然后转换为Datarow然后执行wh在任何时候你需要用它...

Hi,

To fill a Datagrid you need to connect it with any Dataset or Datatable.

To load or save data from Gridview its easy to save the file in to XML or JSON format.

You can also use Dataset to export directly to XML format.

You can travel through the Gridview to make a custom datatable or dataset..

if you don't need to create a datatable or data set, then travel through each rows in the grid and then convert in to Datarow and then do what ever you need to do with it...


Thanks,
Ullas
