在mvc中将Dapper结果QueryMultiple转换为Json的人员？

Question

我有3个选择是这样的。我已经得到所有3选择在SQL转换为JSON。

public IHttpActionResult GetTest() 
{ 
     string sql = $"SELECT 'Ahmad' AS N'Name',\n" + 
     "1 AS N'Code',\n" + 
     "0914 AS N'Phone' FOR JSON PATH\n" + 
     "SELECT 'Alizadeh' AS N'NameFamily',\n" + 
     "2 AS N'Code',\n" + 
     "0915 AS N'Phone' FOR JSON PATH\n" + 
     " \n" + 
     " SELECT 'Seven' AS N'BookName',\n" + 
     "3 AS N'Qty',\n" + 
     "0916 AS N'IBS' FOR JSON PATH"; 
     var info = Connections.QueryMultiple(sql); 
     return Ok(info); 
} 

结果是这样的：

[ 
    { 
    "Name": "Ahmad", 
    "Code": 1, 
    "Phone": 914 
    }, 
    { 
    "NameFamily": "Alizadeh", 
    "Code": 2, 
    "Phone": 915 
    }, 
    { 
    "BookName": "Seven", 
    "Qty": 3, 
    "IBS": 916 
    } 
]
