範例

下列範例會 SqlConnection 建立 和 SqlBatch，然後將多個 SqlBatchCommand 物件新增至批次。 然後它會執行批次，並建立 SqlDataReader。 此範例會讀取批次命令的結果，並將其寫入主控台。 最後，範例會 SqlDataReader 關閉 ，然後在 SqlConnectionusing 區塊落在範圍外時關閉 。

using Microsoft.Data.SqlClient;

class Program
{
    static void Main()
    {
        string str = "Data Source=(local);Initial Catalog=Northwind;"
        + "Integrated Security=SSPI;Encrypt=False";
        RunBatch(str);
    }

    static void RunBatch(string connString)
    {
        using var connection = new SqlConnection(connString);
        connection.Open();

        var batch = new SqlBatch(connection);

        const int count = 10;
        const string parameterName = "parameter";
        for (int i = 0; i < count; i++)
        {
            var batchCommand = new SqlBatchCommand($"SELECT @{parameterName} as value");
            batchCommand.Parameters.Add(new SqlParameter(parameterName, i));
            batch.BatchCommands.Add(batchCommand);
        }

        // Optionally Prepare
        batch.Prepare();

        var results = new List<int>(count);
        using (SqlDataReader reader = batch.ExecuteReader())
        {
            do
            {
                while (reader.Read())
                {
                    results.Add(reader.GetFieldValue<int>(0));
                }
            } while (reader.NextResult());
        }
        Console.WriteLine(string.Join(", ", results));
    }
}
