错误:编译错误:无法在第-1行第-1列分配表达式

Question

我一直在想如何从Map中获取值并将其插入到潜在客户中。这里的某个人非常乐于助人，写了一些代码。但当我试图保存它时，我会出现上面的错误。。。我已经缩小了错误发生的范围。但我不明白为什么它会给我这个错误。

如有任何帮助，我们将不胜感激。下面粗体部分是（我相信）错误的来源。因为当我删除这些行时，我可以保存触发器。

trigger UpdateVerifyLead on Lead (before insert, before update) {
  List<String> leadEmails = new List<String>();
  Map<String, Member_Verification__c > PrimaryEmailMemberVerificationMap = new  Map<String, Member_Verification__c >();
  for(Lead lead:Trigger.new){
      leadEmails.add(lead.Email);
  }
  for(Member_Verification__c member :[SELECT Id, Primary_Email__c,TFA_Salesforce_ID__C FROM Member_Verification__c WHERE Primary_Email__c != null and Primary_Email__c IN :leadEmails]){
      PrimaryEmailMemberVerificationMap.put(member.Primary_Email__c , member);   
  }
  // Problem section start
  for(Lead leadObj:Trigger.new){
      if(PrimaryEmailMemberVerificationMap.ContainsKey(leadObj.Email)){
          lead.TFA_Salesforce_ID__c = PrimaryEmailMemberVerificationMap.get(leadObj.Email).TFA_Salesforce_ID__C ;
          lead.Verified__c = True;
      }
  }
  // Problem section end
}

Answer 1

在外观中有lead.TFA_Salesforce_ID__c和lead.Verified__c。变量lead从未在代码中声明。相反，它应该是for循环中定义的leadObj。例如

for(Lead leadObj:Trigger.new) {
  if(PrimaryEmailMemberVerificationMap.ContainsKey(leadObj.Email)) {
      leadObj.TFA_Salesforce_ID__c = PrimaryEmailMemberVerificationMap.get(leadObj.Email).TFA_Salesforce_ID__C;
      leadObj.Verified__c = True;
  }
}

顺便说一句，Salesforce StackExchange是询问Salesforce特定问题的好地方。
