Question

我正在使用Rest实现WepApi服务，但是我无法浏览它显示无法加载文件或程序集的网址＆＃39; MySql.Data.Entity.EF5，Version = 6.9.0.0，Culture =中性，PublicKeyToken = c5687fc88969c44d＆＃39;或其中一个依赖项。定位的程序集的清单定义与程序集引用不匹配。

IRank.cs enter code here

 interface Icalculation
{
    collection_master AgentRank(int id);
}

Rank.cs

enter code here


   public collection_master AgentRank(int id)
    {


        EntityConnection con = new EntityConnection("name=calculationEntities");
        **con.Open();**
        EntityCommand cmd = new EntityCommand();
        cmd.CommandText = "SELECT Agentid,year(Date_Time) as Year,monthname(Date_Time) as Month,SUM(AmountRecevied) as Amount,@rownum := @rownum + 1 AS Rank FROM collection_master join outstanding_master on collection_master.CustomerID =outstanding_master.CustomerID  and  outstanding_master.PhoneNumber='id',(SELECT @rownum := 0) r GROUP BY AgentID,year(Date_Time),monthname(Date_Time) ORDER BY Amount DESC";



        DbDataReader rdr = cmd.ExecuteReader(CommandBehavior.SequentialAccess);
        collection_master list = new collection_master();
        while (rdr.Read())
        {
            collection_master coll = new collection_master();
            coll.CustomerID = Convert.ToInt32(rdr["CustomerID"]);
            coll.AmountRecevied = Convert.ToInt32(rdr["AmountRecevied"]);
            coll.Date_Time = Convert.ToDateTime(rdr["Date_Time"]);
            coll.Area = rdr["Area"].ToString();
