目前遇到c++调用C#写的DLL 问题，把C#的DLL注册为COM组件，在本机测试完成了，但在客户的机器上无法通过，注册的方式是通过Regasm 去注册dll 和tlb文件 ，但是排查注册表的时候发现未完全注册进去，在其它机器上是否需要加codebase，请各位大神帮帮忙，感谢
C#源码

C#中有调用外部DLL

接口：

[Guid("3965F09B-9EE3-42F7-9908-CCA1BEC8603C")]
public interface ICalc
{
[DispId(1)]
void Join(string a,string b, out string c);
}

类：

[Guid("ABFADDE2-185D-4118-BC54-57458343BD8A")]
[ClassInterface(ClassInterfaceType.None)]
public class Calc:ICalc
{
public void Join(string a, string b, out string c)
{
string url = "tcp://10.1.1.198:8085";
ClientUtils.url = url;
string cc = string.Empty;
//DataSet ds = new DataSet();
//string ssql = "select * from sajet.sys_emp where emp_no = '" + b + "'";
//ds = ClientUtils.ExecuteSQL(ssql);
//if (ds.Tables[0].Rows.Count > 0)
//{
// cc = ds.Tables[0].Rows[0]["EMP_NAME"].ToString();
//}
//else
//{
// cc = "NG";
//}
//c = cc;
//return;
