1. 在属性文件夹下的 Resources.resx 中添加您的图像。（例如 Picture1.jpeg）
2. DataGridViewImageColumn在你的添加一个DataGridView

3. 以这种方式添加图像：

   for (int row = 0; row <= [YourDataGridViewName].Rows.Count - 1; row++)
   {
       ((DataGridViewImageCell)gvFiles.Rows[row].Cells[1]).Value = Properties.Resources.Picture1
   }

        for (int row = 0; row < dataGridView1.Rows.Count - 1; row++)
        {
            Bitmap bmp = new Bitmap(Application.StartupPath + "\\Data\\AirPlaneData\\" + dt.Rows[row][4]);
            ((DataGridViewImageCell)dataGridView1.Rows[row].Cells[5]).Value = bmp;
        }

string FileName = null;

OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.RestoreDirectory = true;

openFileDialog.Filter = "All picture files (*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF";

将图像作为资源添加到您的项目中，并应用以下代码

DataGridViewImageColumn btnDel = new DataGridViewImageColumn();
btnDel.Name = "DelCourrier";
btnDel.HeaderText = "";
btnDel.Image = Properties.Resources.delete;// delete is the name of the image added as ressource
dataGridView1.Columns.Add(btnDel);
