使用Dapper.TVP TableValueParameter和其他参数

I have a procedure that takes in a table-valued parameter, along with others:

我有一个过程，它接受一个表值参数，以及其他：

CREATE PROCEDURE [dbo].[Update_Records]
    @currentYear INT,
    @country INT,
    @records Record_Table_Type READONLY
AS

and am trying to call this with Dapper.TVP.

我试图用Dapper.TVP来调用它。

Here is the code I have so far:

这是我到目前为止的代码：

        var recordsParameter = new List<SqlDataRecord>();

        // This metadata matches 'Record_Table_Type' in the Database
        var recordsMetaData = new[]
        {
            new SqlMetaData("OriginalValue", SqlDbType.Decimal, 19, 4),
            new SqlMetaData("NewValue", SqlDbType.Decimal, 19, 4),
            new SqlMetaData("NewPercent", SqlDbType.Decimal, 7, 2),
        };

        foreach (var r in records)
        {
            var record = new SqlDataRecord(recordsMetaData);
            record.SetDecimal(0, r.OriginalValue);
            record.SetDecimal(1, r.NewValue);
            record.SetDecimal(2, r.NewPercent);
            recordsParameter.Add(record);
        }

        var spParams = new DynamicParameters(new
        {
            currentYear = filter.currentYear,
            country = filter.country,
        });

        var recordsParam = new TableValueParameter("@records", "Record_Table_Type", recordsParameter);

        using (var connection = ConnectionFactory.GetConnection())
        {
            connection.Execute("Update_Records", ???, commandType: CommandType.StoredProcedure);
        }

My issue is how do I pass both sets of parameters to the procedure in the call to Dapper Execute()?

我的问题是如何在调用Dapper Execute（）时将两组参数传递给过程？

I have tried:

我努力了：

var spParams = new DynamicParameters(new
{
    currentYear = filter.currentYear,
    country = filter.country,
    records = new TableValueParameter("@records", "Record_Table_Type", recordsParameter);
});

connection.Execute("Update_Records", spParams, commandType: CommandType.StoredProcedure);

and

和

connection.Execute("Update_Records", new Object[] { spParams, recordsParam }, commandType: CommandType.StoredProcedure);

Both call the procedure, but pass an empty table parameter ( SELECT COUNT(*) FROM @records returns 0 )

两者都调用该过程，但传递一个空表参数（SELECT COUNT（*）FROM @records返回0）

I can't seem to find any actual documentation or source for Dapper.TVP, so the whole thing is very confusing, and the 2nd parameter to .Execute() is just a dynamic so that again doesn't tell me what I can and can't pass to it.

我似乎无法找到Dapper.TVP的任何实际文档或来源，所以整个事情非常令人困惑，而.Execute（）的第二个参数只是一个动态，所以再次没有告诉我我能做什么无法传递给它。

Any ideas?

有任何想法吗？

I am on mobile and may be misunderstanding the question, but this should be just:

我在移动设备上并且可能误解了这个问题，但这应该只是：

DataTable records = ...
connection.Execute("Update_Records",
    new {
        currentYear = filter.currentYear,
        country = filter.country,
        records
    },
    commandType: CommandType.StoredProcedure
);

Based on an answer from Mark Gravell here: Does Dapper support SQL 2008 Table-Valued Parameters?

基于Mark Gravell的回答：Dapper是否支持SQL 2008表值参数？

I changed my code to no longer use Dapper.TVP and instead just use a DataTable so the code is now:

我改变了我的代码，不再使用Dapper.TVP而只是使用DataTable，所以代码现在是：

        var recordsTable = new DataTable();
        recordsTable.Columns.Add("NewValue", typeof(Decimal));
        foreach (var netRevenue in records)
        {
            var row = recordsTable.NewRow();
            row[0] = netRevenue.NewValue;
            recordsTable.Rows.Add(row);
        }
        recordsTable.EndLoadData();

        var spParams = new DynamicParameters(new
        {
            currentYear = filter.currentYear,
            country = filter.country,
            records = recordsTable.AsTableValuedParameter("Record_Table_Type")
        });

        using (var connection = ConnectionFactory.GetConnection())
        {
            connection.Execute("Update_Records", spParams, commandType: CommandType.StoredProcedure);
        }

And this works.

这很有效。
