AssemblyInfo.cs中须做以下设置：

b.[assembly: AllowPartiallyTrustedCallers()]

3.生成的证书能正常在IE下安装，需继承IObjectSafety，考虑到所有的生成的证书都需继承自该接口，需写一个基类，代码如下：
a.接口代码：

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace LamSoonActivex
{
    [ComImport, Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    interface IObjectSafety
    {
        [PreserveSig]
        int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

        [PreserveSig()]
        int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
    }
}
