远程过程调用(RPC)协议流不正确

Laj*_*jos 7 .net c# t-sql wpf entity-framework

我使用entityframework 5.0.我有这么多考试.如果我单独进行测试就会通过,如果我在同一时间与其他人一起运行它,它就不会通过.测试之间没有联系.每次发送一个相同的查询.它不会被修改.

当我尝试插入具有浮点数据类型的新行时,我遇到了这个问题.当我尝试插入(无穷大)或(NaN)值时抛出此异常,并且SOL Server不支持这些值.

如果您使用Entity Framework,建议使用(http://hibernatingrhinos.com/products/EFProf/learn/).跟踪生成的SQL.并检测导致您的问题的参数.

如果您使用TPT(Table-Per-Type), SQL事件探查器将无法帮助您.

我正在发出带有选择命令的 SQLCommand 并且出现错误：

传入的表格数据流 (TDS) 远程过程调用 (RPC) 协议流不正确。RPC 名称无效。

因为我正在调用命令类型为 的 SQLCommand CommandType.StoredProcedure。

改变这个来CommandType.Text解决我的问题。

System.Data.SqlClient.SqlCommand result = new SqlCommand(GetSQLSelectCommande());
        if (FromDate == default(DateTime) || isEqualDay(FromDate, DateTime.Now))
        {
            FromDate.AddMonths(-1);
        }
        ToDate = new DateTime(ToDate.Year, ToDate.Month, ToDate.Day, 23, 59, 59);
        result.Parameters.Clear();
        result.CommandType = CommandType.Text;
        result.Parameters.Add("@IdClient", SqlDbType.Int).Value = this.IdClient;
        result.Parameters.Add("@dateDebut", SqlDbType.DateTime).Value = this.FromDate;
        result.Parameters.Add("@dateFin", SqlDbType.DateTime).Value = this.ToDate;
        result.Parameters.Add("@langue", SqlDbType.Int).Value = (Offix.Culture.GetCulture() == Offix.EnumLangue.ofxFrancais ? 5 : 3);

我认为问题出在你的参数上@6。看来格式无效。
您是否尝试过类似的方法来创建日期？:

new DateTime(1991,07,04).ToShortDateString()
