当在 amd64 环境下调用收集数据方法时有异常，我参考了别人的代码更改如下并测试通过

文件路径为：\CTPSharp\CTPTradeApi\DataCollect.cs

public DataCollect()
{
    try
    {
        string path = Path.GetFullPath(string.Format("{0}\\{1}", LibraryWrapper.ProcessorArchitecture,
                DllName));
        _wrapper = new LibraryWrapper(path);

        if(LibraryWrapper.ProcessorArchitecture == "x86") {
            getSystemInfo = _wrapper.GetUnmanagedFunction<DelegateGetSystemInfo>("?CTP_GetSystemInfo@@YAHPADAAH@Z");
        } else {
            getSystemInfo = _wrapper.GetUnmanagedFunction<DelegateGetSystemInfo>("?CTP_GetSystemInfo@@YAHPEADAEAH@Z");
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}
