Answer 1

您可以直接在网格视图中添加图像列。.因此，您无需在dt中添加图像列。可以这样做

    GridName.Columns.Clear()
    Dim ds As DataSet = SqlHelper.ExecuteDataset(connect(), CommandType.StoredProcedure, ProcedureName, Parameter)
    Dim DT As DataTable = ds.Tables(0)
    GridName.DataSource = DT
    Dim img As New DataGridViewImageColumn()
    Dim inImg As System.Drawing.Image = My.Resources.edit
    img.Image = inImg
    img.HeaderText = "Edit"
    img.ToolTipText = "Edit"
    GridName.Columns.Add(img)
    img.DefaultCellStyle.BackColor = System.Drawing.Color.MediumAquamarine
