C# 用数据库中的值替换字符串中的代码

我正在替换字符串中的一些代码。我有一个函数，可以从emailtemplates表中获取电子邮件模板，其中包含一些代码，如

###NewUserFirstName##

和

###

在该表的body列中。还有一个表定义了从哪个表中替换这些代码的值，所以对于

##NewUserFirstName##

我在第二个表中定义了

UserProfile.FirstName

和

#password##

UserProfile.password

。我有如下所有合并代码：

  using (IMailMergeCodeManager mailMergeCodeManager = new ManagerFactory().GetMailMergeCodeManager())
    {
        mailMergeCodes = mailMergeCodeManager.GetAll().ToList();
    }

 using (ICampaignManager campaignManager = new ManagerFactory().GetCampaignManager())
 {
     using (IUserProfileManager UserProfileManager1 = new ManagerFactory().GetUserProfileManager())
     {
         using (IAccountManager AccountManager = new ManagerFactory().GetAccountManager())
         {
             using (ICallTypeManager CallTypeManager = new ManagerFactory().GetCallTypeManager())
             {
                 using (ICallOutcomeManager CallOutComeManager = new ManagerFactory().GetCallOutcomeManager())
                 {
                     using (ICallRecordingManager CallRecordingManager = new ManagerFactory().GetCallRecordingManager())
                     {
                         UserProfile UserProfile = UserProfileManager1.GetByfkAccountId(Convert.ToInt32(AccountId)).FirstOrDefault();
                         Account acc = AccountManager.GetById(Convert.ToInt32(AccountId));                                      
                         UserProfile CurrentLoggedInUser = UserProfileManager1.GetByfkAccountId(Convert.ToInt32(CurrentAccount.Id)).FirstOrDefault();
                         CallRecording callRecording = CallRecordingManager.GetById(callRecordingId);

                         if (subject.Contains("##password##") || body.Contains("##password##"))
                             password = GetPassword(UserProfile.UserAuthentication.EmailAddress);


                         foreach (MailMergeCode mergeCode in mailMergeCodes)
                         {
                             if (body.Contains(mergeCode.MailMerge)) 
                                 body = Regex.Replace(body, mergeCode.MailMerge, mergeCode.FieldName, RegexOptions.IgnoreCase);


                             if (subject.Contains(mergeCode.MailMerge) && !subject.Contains("##password##"))
                                 subject = Regex.Replace(subject, mergeCode.MailMerge, mergeCode.FieldName, RegexOptions.IgnoreCase);

                         }

                     }
                 }
             }
         }
     }

 }

现在，我用以下代码替换模板中的代码：

  using (IMailMergeCodeManager mailMergeCodeManager = new ManagerFactory().GetMailMergeCodeManager())
    {
        mailMergeCodes = mailMergeCodeManager.GetAll().ToList();
    }

 using (ICampaignManager campaignManager = new ManagerFactory().GetCampaignManager())
 {
     using (IUserProfileManager UserProfileManager1 = new ManagerFactory().GetUserProfileManager())
     {
         using (IAccountManager AccountManager = new ManagerFactory().GetAccountManager())
         {
             using (ICallTypeManager CallTypeManager = new ManagerFactory().GetCallTypeManager())
             {
                 using (ICallOutcomeManager CallOutComeManager = new ManagerFactory().GetCallOutcomeManager())
                 {
                     using (ICallRecordingManager CallRecordingManager = new ManagerFactory().GetCallRecordingManager())
                     {
                         UserProfile UserProfile = UserProfileManager1.GetByfkAccountId(Convert.ToInt32(AccountId)).FirstOrDefault();
                         Account acc = AccountManager.GetById(Convert.ToInt32(AccountId));                                      
                         UserProfile CurrentLoggedInUser = UserProfileManager1.GetByfkAccountId(Convert.ToInt32(CurrentAccount.Id)).FirstOrDefault();
                         CallRecording callRecording = CallRecordingManager.GetById(callRecordingId);

                         if (subject.Contains("##password##") || body.Contains("##password##"))
                             password = GetPassword(UserProfile.UserAuthentication.EmailAddress);


                         foreach (MailMergeCode mergeCode in mailMergeCodes)
                         {
                             if (body.Contains(mergeCode.MailMerge)) 
                                 body = Regex.Replace(body, mergeCode.MailMerge, mergeCode.FieldName, RegexOptions.IgnoreCase);


                             if (subject.Contains(mergeCode.MailMerge) && !subject.Contains("##password##"))
                                 subject = Regex.Replace(subject, mergeCode.MailMerge, mergeCode.FieldName, RegexOptions.IgnoreCase);

                         }

                     }
                 }
             }
         }
     }

 }

}

但下面的行将

##NewUserFirstName##

设置为

UserProfile.FirstName

body=Regex.Replace（body，mergeCode.MailMerge，mergeCode.FieldName，RegexOptions.IgnoreCase）

而不是从
UserProfile.FirstName
即“Joe Smith”获取值

如何解决此问题？
使用此代码如果您有任何问题，请告诉我

if (Body.Contains(""##password##""))
 {
 Body = Body.Replace(""##password##"", yourpassword_string);
 }

您是否使用了string.replace让我知道这是否解决了您的问题Hi@Skhurams:我正在尝试将mergeCode.MailMerge替换为mergeCode.FieldName，其中mergeCode.MailMerge是##NewUserFirstName###，mergeCode.FieldName是UserProfile.FirstName，但我希望UserProfile.FirstName的值为“Joe smith”当您向主题和主体添加字符串时，请使用我提到的代码替换字符串
