开发环境：vs2005 + MapXtreme2005
写下一点经验，供参考：

页面的代码：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" Inherits="Default2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

</head>

<body>

<div>

<table>

<tr>

<td>

<img src="<%=m_strImg%>" alt="" style="width: 900px; height: 800px" id="MapControl1_Image" />

</td>

</tr>

<tr>

<td>

</td>

</tr>

</table>

</div>

</form>

</body>

</html>

后台代码：

using System;

using System.Data;

using System.Configuration;

using System.Collections;

using System.Web;

using System.Web.Security;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using MapInfo.WebControls;

using System.IO;

using ApplicationStateManager;

public partial class Default2 : System.Web.UI.Page

{

protected string m_strImg = "";

protected void returnImage()

{

MapControlModel model = MapControlModel.GetModelFromSession();

if (model == null) model = MapControlModel.SetDefaultModelInSession();

MemoryStream ms = null;

try

{

ms = model.GetMap("Map1", 900, 800, "Gif");

}

catch (Exception ex)

{

HttpContext.Current.Server.ClearError();

return;

}

// Insert the image stream to Cache with key imageid and timeout in 2 mintues.

string imageid = ImageHelper.GetUniqueID();

ImageHelper.SetImageToCache(imageid, ms, 2);

m_strImg = ImageHelper.GetImageURL(imageid, "Gif");

}

private void Page_Load(object sender, System.EventArgs e)

{

// If the StateManager doesn't exist in the session put it else get it.

if (StateManager.GetStateManagerFromSession() == null)

StateManager.PutStateManagerInSession(new AppStateManager());

// Now Restore State

StateManager.GetStateManagerFromSession().ParamsDictionary[StateManager.ActiveMapAliasKey] = "Map1";

StateManager.GetStateManagerFromSession().RestoreState();

returnImage();

}

// At the time of unloading the page, save the state

private void Page_UnLoad(object sender, System.EventArgs e)

{

StateManager.GetStateManagerFromSession().SaveState();

}

配置文件：
<add key="MapInfo.Engine.Session.Workspace" value="C:/Program Files/MapInfo/MapXtreme/6.6/Samples/Data/World.mws" />

按照上述步骤就完成了地图的显示。
