通过读byte数组用Image控件显示一个图画，如何实现？

谢谢各位的帮助，byte数组里面得数据已经有了，就书读出来，再用Image控件显示

对，用一个页面去读图片，然后ImageUrl=yourshowImgPage.aspx

就是把byte数组读出来，用Image控件显示，很急！！！！！！

页面qqq.aspx
private void Page_Load(object sender, System.EventArgs e)
{
if (Session["LoginName"] == null)
{
Response.Write("页面过期，请重新登录！");
Response.End();
}
if (!Page.IsPostBack)
{
SqlConnection connstr = new SqlConnection(ConfigurationSettings.AppSettings["sqlconnstring"]);
string imgid = Request.QueryString["id"];
string sql = "";
if (Request.QueryString["colid"] == "0")
{
sql="SELECT * FROM contractview WHERE id = '"+imgid+"'";
}
if (Request.QueryString["colid"] == "1")
{
sql="SELECT * FROM contractchildview WHERE id = '"+imgid+"'";
}
SqlCommand command = new SqlCommand(sql, connstr);
connstr.Open();
SqlDataReader dr = command.ExecuteReader();
try
{
while(dr.Read())
{
Response.BinaryWrite( (byte[]) dr["side"] );
Response.Write("<br>");
}
}
catch
{
ShowErrMsg("此合同评审记录没有附件");
return;
}
connstr.Close();
}
}
然后把此页面邦定到img控件,例如,自己改改，给你个思路！
<img src="qqq.aspx">

<asp:Image Runat=server ID="Image1" Width="150" Height="125"
ImageUrl=abc.aspx?ID=234 />
.....
abc.aspx:
Public Sub Page_Load(sender As Object, e As EventArgs)
Dim strImageID as String = Request.QueryString("id")
Dim myConnection As New SqlConnection("Data Source=.;Initial Catalog=mxh;User Id=sa;Password=;")
Dim myCommand As New SqlCommand("Select PersonImageType, PersonImage from Person Where PersonID=" _
+ strImageID, myConnection)

Try
myConnection.Open()
Dim myDataReader as SqlDataReader
myDataReader = myCommand.ExecuteReader(CommandBehavior.CloseConnection)
Do While (myDataReader.Read())
Response.ContentType = myDataReader.Item("PersonImageType")
Response.BinaryWrite(myDataReader.Item("PersonImage"))
Loop
myConnection.Close()
Catch SQLexc As SqlException
End Try
End Sub
