获取到图片之后显示的带有路径地址，我截取并没有截掉请问怎么做才好？代码如下

private void Form3_Load(object sender, EventArgs e)
{
DataTable tbl = AccessHelper.ExecuteDataTable("select Pictrue from obs");
DataTable tbl1 = AccessHelper.ExecuteDataTable("select Name from obs");
//this.listView1.Items.Clear();
//this.imageList1.Images.Clear();6
for (int i = 0; i < tbl.Rows.Count; i++)
{
Image img = Image.FromFile(tbl.Rows[i][0].ToString());
imageList1.Images.Add(img);
listView1.Items.Add(tbl.Rows[i][0].ToString(), i);

string str = @"C:\myfile\obs\鱼类\2.jpg".Replace(@"C:\myfile\obs\鱼类\.jpg", "");
}

}
