试图将字符串，但得到的错误

HI我想这些字符串连接在一起，但我在这行试图将字符串，但得到的错误

sql += " "+"WHERE memberToMship_PayMethod="' +Cash"'";

喜欢太多的字符在字符文字....

有错误可以在任何在这一个帮助PLS ......

       sql = @"SELECT members.member_Id, members.member_Lastname, members.member_Firstname, members.member_IsBiometric"; 
    sql += ","+"members.member_Reference, members.member_Dob, members.member_PostCode, mshipstatustypes.mshipStatusType_Name, mshiptypes.mshipType_Name"; 
    sql += ","+"membertomships.memberToMship_EndDate"; 
    sql += " "+"FROM members LEFT JOIN membertomships ON membertomships.member_Id = members.member_Id"; 
    sql += " "+"LEFT JOIN mshipstatustypes ON mshipStatusType_Id = membertomships.mshipStatusType_Id"; 
    sql += " "+"LEFT JOIN mshipoptions ON mshipoptions.mshipOption_Id = membertomships.mshipOption_Id"; 
    sql += " "+"LEFT JOIN mshiptypes ON mshiptypes.mshipType_Id = mshipoptions.mshipType_Id"; 
    sql += " "+"WHERE memberToMship_PayMethod="' +Cash"'";

凭啥你串联'”‘'和'’议员......‘'，而不是仅仅做'’议员...“' – Jacob

现金是列值之一 – user682417

如果可能，你会重新格式化吗？ – user682417

sql += " "+"WHERE memberToMship_PayMethod="' +Cash"'";

也许应该

sql += " "+"WHERE memberToMship_PayMethod='" +Cash+ "'";

或

sql += " "+"WHERE memberToMship_PayMethod='Cash'";

我得到了像”现金是不存在的“错误 – user682417

很多谢谢..它的工作很好.. – user682417

哇，你真的有点盲目地把东西砸在一起，对吗？ ;-) –

你有一个报价外双引号，和你错过+。试试这个：

sql += " "+"WHERE memberToMship_PayMethod='" + Cash + "'";

错过了一个+现金后:) – niktrs

尝试

 sql = @"SELECT members.member_Id, members.member_Lastname, members.member_Firstname, members.member_IsBiometric"; 
    sql += ","+"members.member_Reference, members.member_Dob, members.member_PostCode, mshipstatustypes.mshipStatusType_Name, mshiptypes.mshipType_Name"; 
    sql += ","+"membertomships.memberToMship_EndDate"; 
    sql += " "+"FROM members LEFT JOIN membertomships ON membertomships.member_Id = members.member_Id"; 
    sql += " "+"LEFT JOIN mshipstatustypes ON mshipStatusType_Id = membertomships.mshipStatusType_Id"; 
    sql += " "+"LEFT JOIN mshipoptions ON mshipoptions.mshipOption_Id = membertomships.mshipOption_Id"; 
    sql += " "+"LEFT JOIN mshiptypes ON mshiptypes.mshipType_Id = mshipoptions.mshipType_Id"; 
    sql += " "+"WHERE memberToMship_PayMethod='" + "Cash" + "'";

其实你不需要concate，您查询是简单的，所以你可以使用：

sqlQuery = @"Select * from ........... 
.......................... 
where CashMethod="+Cash;
