Question

我有逐字字符串有一些变量contacanete with，我的问题我总是从编译器得到这个错误：

; expected

那我怎么能正确地逃脱呢？

int teacherId = sqlStatus = (int)sqlCmd.LastInsertedId;
sqlCmd.CommandText = @"INSERT INTO report (report_type, report_date, semester, report_details, teacher_id) 
                            VALUES (0, ""2018-01-01"", 1, '{
                              ""teacherId"": "" " + teacherId.ToString() + " "",   <=== error here (; expected)
                              ""mahderDate"": """",
                              ""teacherShool"": """",
                              ""baladia"": """",
                              ""wilaya"": """",
                              ""moufatecheReport"": """"
                            }'," + teacherId + ");";

使用@poke建议我设法让它在行中放置双引号和@：

    int teacherId = sqlStatus = (int)sqlCmd.LastInsertedId;
    sqlCmd.CommandText = @"INSERT INTO report (report_type, report_date, semester, report_details, teacher_id) 
                                VALUES (0, ""2018-01-01"", 1, '{
                                  ""teacherId"": "" " + teacherId.ToString()  + "," + 
                               @" ""mahderDate"": """",
                                  ""teacherShool"": """",
                                  ""baladia"": """",
                                  ""wilaya"": """",
                                  ""moufatecheReport"": """"
                                }'," + teacherId + ");";
