C#编写COM组件
一.先创建类库项目
二.Project-》Property-》Application-》Assembly Information-》Make Assembly Com Visiable
三.Property-》Build->Register for Com Interop
四.Property-》Signing-》Create a new key
五.编码
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Text;
usingSystem.Runtime.InteropServices;
namespaceCOMCOM
{
[ComVisible(true)]
[Guid("2CBD3D76-35F1-4f9d-9C1B-9DBFEE412F76")]
publicinterfaceIMarcus
{
void Initialize();
void Dispose();
int Add(int x, int y);
}
[ComVisible(true)]
[Guid("EA2F140A-108F-47ae-BBD5-83EEE646CC0D")]
publicclassComForMarcus:IMarcus
{
#regionIMarcus Members
publicvoid Initialize()
{
//throw new NotImplementedException();
}
publicvoid Dispose()
{
//throw new NotImplementedException();
}
publicint Add(int x, int y)
{
return x + y;
}
#endregion
}
}
六.Visual Studio Command Prompt-》regasm COMCOM.dll 注册成功，可以在OLE/COM Object Viewer中查看
Javascript call Com：
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script type="text/javascript">
function callCom() {
var comObj = new ActiveXObject("COMCOM.ComForMarcus");
var result = comObj.Add(22, 33);
alert(result);
}
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<input id="Button1" type="button" value="button" onclick="callCom();" />
</div>
</form>
</body>
</html>
需要在IE安全设置中启用不安全的ActiveX控件，才能正确显示。
