如何在单击按钮时从datagridview中的sqlserver检索所有类型的数据？

Question

I want to know how I can retrieve image's from sqlserver in DataGridView on a button click. I can show other types of data with the following code and at image column it is showing error. So how can I show all types of data column-wise in DataGridView on button click including image in c#.

private void ViewButton_Click(object sender, EventArgs e)
{
    SqlConnection connection = new SqlConnection("Data Source=DESKTOP-FQBMN3R\\SQLEXPRESS;Initial Catalog=StudentDB; Integrated Security=true");
    connection.Open();
    SqlDataAdapter sd = new SqlDataAdapter("select *  from tbl_student_info", connection);

    DataSet ds = new DataSet();
    sd.Fill(ds, "tbl_student_info");
    ViewDataGridView.DataSource = ds.Tables[0];

    connection.Close();
}

Answer 1

The SQL datatype image is returned as a byte[] in c#. To turn this into an actual image you'd do something like this:

var imgArray = (byte[])ds.Tables[0].Rows[0]["FILE_IMAGE"];
using (var s = new MemoryStream(imgArray))
{
    var img = System.Drawing.Image.FromStream(s);
}
