1、添加组件
　　打开VS2008，工具-选择工具箱项-COM组件，勾选Shockwave Flash Object，确定。

2、将Flash组件放入窗体中
　　将工具箱中的Shockwave Flash Object组件拖放到窗体中，设置其属性。

3、as代码

import flash.external.ExternalInterface;

//向C#发送数据
if (ExternalInterface.available)
{
    var strResult:String = ExternalInterface.call("userValidate", userid, password);
}


//接收C#返回的结果
if (ExternalInterface.available)
{
    ExternalInterface.addCallback("userValidate", userValidate);
}

//根据C#返回的结果处理
public function userValidate(str:String):void
{
    trace(str);
}

4、c#代码

public mainForm()
{
    InitializeComponent();
    mainFlash.Movie = Application.StartupPath + "\\swf\\DayBook.swf";//设置flash地址
    mainFlash.Menu = false;
    mainFlash.FlashCall += new AxShockwaveFlashObjects._IShockwaveFlashEvents_FlashCallEventHandler(mainFlash_FlashCall);
}

private void mainFlash_FlashCall(object sender, AxShockwaveFlashObjects._IShockwaveFlashEvents_FlashCallEvent e)
{
    XmlDocument document = new XmlDocument();
    document.LoadXml(e.request);
    XmlAttributeCollection attributes = document.FirstChild.Attributes;

    // 获取函数名
    String command = attributes.Item(0).InnerText;

    // 获取参数
    XmlNodeList list = document.GetElementsByTagName("arguments");
    int count = list[0].ChildNodes.Count;//参数数量
    string[] arr_paras = new string[count];
    //处理参数
    for (int i = 0; i < count; ++i)
    {
        arr_paras[i] = list[0].ChildNodes[i].InnerText.ToString();
    }

    switch (command)
    {
       case "userValidate":
             userValidate(arr_paras, "userValidate");
             break;
       case "getPeopleList":
             getPeopleList(arr_paras, "getPeopleList");
             break;
    
     }
}

//C#传给Flash的值
private void callFunction(string funName, string arg)
{
    //funName：调用as中的函数
    //arg：参数
    mainFlash.CallFunction("<invoke name=\"" + funName + "\" returntype=\"xml\"><arguments><string>" + arg + "</string></arguments></invoke>");
}

//登录验证
public void userValidate(string[] arr_data, string functionName)
{
    string password = arr_data[1];
    password = OperClass.Encrypt(password, 1);
    string sql = "select id,username from users where state='0' and userid=" + OperClass.str(arr_data[0]) + " and password=" + OperClass.str(password);
    DataSet ds = dbc.ExecuteSqlDsForAccess(sql, "info");

    string result = "";
    if (ds != null && ds.Tables["info"].Rows.Count > 0)
    {
        result = ds.Tables["info"].Rows[0]["id"].ToString() + "㊣" + ds.Tables["info"].Rows[0]["username"].ToString();
    }
    else
    {
        result = "-1";
    }
    callFunction(functionName, result);
}
