使用ado.net

Question

当我尝试使用ado.net运行存储过程时，我得到了一些非常奇怪的结果。我已使用EXEC dbo.AddressSearch验证存储过程是否正确执行。

public DataTable ExecuteStoredProcedure(string name, params SqlParameter[] parameters)
{
        var dataTable = new DataTable();
        var mode = _configurationService.AppSetting("mode");
        var connectionString = _configurationService.ConnectionString($"{mode}ConnectionString");

        using (var sqlConnection = new SqlConnection(connectionString))
        {
            sqlConnection.Open();

            using (var command = new SqlCommand(name,sqlConnection))
            {
                foreach (var parameter in parameters)
                {
                    command.Parameters.AddWithValue(parameter.ParameterName, parameter.Value);
                }

                using (var dataAdapter = new SqlDataAdapter(command))
                {
                    dataAdapter.Fill(dataTable);
                }
            }
        }

        return dataTable;
}

以下是调用存储过程的代码;我已经验证它正在使用SQL Server Profiler调用存储过程。以下是它发送的内容：

exec sp_executesql 
N'AddressSearch',
N'@PageSize int,
@Start int,
@StreetName nvarchar(4000),
@Notes nvarchar(4000),
@ParcelNumber nvarchar(4000),
@ZoningCode nvarchar(4000),
@HouseNumber nvarchar(2),
@County nvarchar(4000),
@Municipality nvarchar(4000)
,@SubDivision nvarchar(4000)',
@PageSize=50,
@Start=1,
@StreetName=N'',
@Notes=N'',
@ParcelNumber=N'',
@ZoningCode=N'',
@HouseNumber=N'12',
@County=N'',
@Municipality=N'',
@SubDivision=N''

所以我用SSMS调试了这个，我注意到没有设置变量。谁能告诉我为什么会这样呢？

Json被派遣。

{
    "county":"",
    "esn":"",
    "houseNumber":"12",
    "municipality":"",
    "notes":"",
    "page":"1",
    "pageSize":"50",
    "parcelNumber":"",
    "start":"0",
    "streetName":"",
    "subDivision":"",
    "uniqueId":"",
    "zoningCode":""
}

填充所有json：

{
    "county":"a",
    "esn":"12",
    "houseNumber":"12",
    "municipality":"",
    "notes":"notes",
    "page":"1",
    "pageSize":"50",
    "parcelNumber":"abd",
    "start":"0",
    "streetName":"3",
    "subDivision":"sub",
    "uniqueId":"1",
    "zoningCode":"15"
}

发送到SQL Server：

exec sp_executesql N'AddressSearch',N'@PageSize int,@Start int,@StreetName nvarchar(1),@Notes nvarchar(5),@ParcelNumber nvarchar(3),@ZoningCode nvarchar(2),@HouseNumber nvarchar(2),@County nvarchar(1),@Municipality nvarchar(4000),@SubDivision nvarchar(3),@Esn int,@UniqueId int',@PageSize=50,@Start=0,@StreetName=N'3',@Notes=N'notes',@ParcelNumber=N'abd',@ZoningCode=N'15',@HouseNumber=N'12',@County=N'a',@Municipality=N'',@SubDivision=N'sub',@Esn=12,@UniqueId=1

存储过程：

    DROP PROCEDURE dbo.AddressSearch
GO
