c# - 如何将类型'string'转换为system.drawing.image

Question

我只想像其他数据一样从数据库中获取图像到图片框中。我该怎么做？

private void dataGridView1_MouseDoubleClick(object sender, MouseEventArgs e)
{
      //shows the data on fields if click on the entries 
      //on sequence in which the query is 

      IDtxt.Text = dataGridView1.SelectedRows[0].Cells[0].Value.ToString();
      NAMEtxt.Text = dataGridView1.SelectedRows[0].Cells[1].Value.ToString();
      F_Nametxt.Text = dataGridView1.SelectedRows[0].Cells[2].Value.ToString();
      BLOODc_box .Text  = dataGridView1.SelectedRows[0].Cells[3].Value.ToString();
      CNICtxt .Text = dataGridView1.SelectedRows[0].Cells[4].Value.ToString();
            
      GENDERc_box .Text  = dataGridView1.SelectedRows[0].Cells[5].Value.ToString();
      CONTACTtxt.Text = dataGridView1.SelectedRows[0].Cells[6].Value.ToString();
      JOBtitleText.Text = dataGridView1.SelectedRows[0].Cells[7].Value.ToString();
      SALARYtxt.Text = dataGridView1.SelectedRows[0].Cells[8].Value.ToString();
      ADDRESStxt.Text = dataGridView1.SelectedRows[0].Cells[9].Value.ToString();
      AGEtxt .Text  = dataGridView1.SelectedRows[0].Cells[10].Value.ToString();
      pictureBox1 .Image   =  dataGridView1.SelectedRows[0].Cells[11].Value.ToString();

}

如果你有 base64 字符串，那么试试这个

var image = GetImage("yourBase64String");

public Image GetImage(string value)
{        
    byte[] bytes = Convert.FromBase64String(value);
    Image image;
    using (MemoryStream ms = new MemoryStream(bytes))
    {
        image = Image.FromStream(ms);
    }
    return image;
}
