我现在做一个安装包,其中要注册组件服务。请问怎么写;  
 
 
 
                     try  
                       {  
                               string  applicationName  =  "MyApp";  
                               string  typeLibraryName  =  null;  
                               RegistrationHelper  helper  =  new  RegistrationHelper();  
                               //  takes  precedence  over  the  application  name  you  provide  to  InstallAssembly.    
                               helper.InstallAssembly(@"C:\RCOM.dll",  ref  applicationName,  ref  typeLibraryName,  InstallationFlags.CreateTargetApplication);  
                               this.label1.Text  =  "Registration  succeeded:  Type  library  {0}  created."  +  typeLibraryName;  
 
                               RegistrationConfig  registrationConfiguration  =  new  RegistrationConfig();  
                               registrationConfiguration.AssemblyFile  =  @"C:\RCOM.dll";  
                               registrationConfiguration.Application  =  "MyApp";  
                               registrationConfiguration.InstallationFlags  =  InstallationFlags.CreateTargetApplication;  
                               RegistrationHelper  helperFromConfig  =  new  RegistrationHelper();  
                               helperFromConfig.InstallAssemblyFromConfig(ref  registrationConfiguration);  
                       }  
                       catch  (RegistrationException  e1)  
                       {  
                               this.textBox1.Text  =  e1.ToString();  
                       }  
 
 
上面是我写的,总是报错:System.EnterpriseServices.RegistrationException:  加载程序集“c:\RCOM.dll”失败。  --->  System.BadImageFormatException:  未能加载文件或程序集“file:///c:\RCOM.dll”或它的某一个依赖项。该模块应包含一个程序集清单。

另上面的C:\RCOM.dll怎么写成相对路经;
