asp.net图片上传实例

第一、图片上传，代码如下：
xxx.aspx

 <td class="style1">
                <asp:FileUpload ID="FileUpload1" runat="server"  />
                <asp:Button ID="Button1" runat="server" Text="上传一般图片" onclick="Button1_Click" />
            </td>
            <td class="style3">
                <asp:Image ID="Image1" runat="server" Height="200px" Width="200px" />
            </td>
</div>
xxx.aspx.cs

                            this.Image1.ImageUrl = "upload/" + AtterFileName;
                        }
                    }
                    else
                    {
                        Response.Write("<script>alert('该文件不是图片格式！');</script>");
                    }
                }
                else
                {
                    Response.Write("<script>alert('请选择要上传的图片');</script>");
                }

            }
        }
</div>

第二、添加文字水印的图片上传，代码如下：
xxx.aspx

 <td class="style1">
                <asp:FileUpload ID="FileUpload2" runat="server" />
                <asp:Button ID="Button2" runat="server" Text="上传文字图片" onclick="Button2_Click" />
            </td>
            <td>
                <asp:Image ID="Image2" runat="server" Height="200px" Width="200px" />
            </td>
</div>
xxx.aspx.cs
