如何从存储过程填充DataTable

using System.Data;
using System.Data.SqlClient;

public DataTable FillDataTableFromStoredProcedure(string connectionString, string storedProcedureName)
{
    DataTable dataTable = new DataTable();

    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        using (SqlCommand command = new SqlCommand(storedProcedureName, connection))
        {
            command.CommandType = CommandType.StoredProcedure;

            connection.Open();

            using (SqlDataReader reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    DataRow row = dataTable.NewRow();

                    // 根据存储过程返回的列名获取每列的值
                    row["ColumnName1"] = reader["ColumnName1"];
                    row["ColumnName2"] = reader["ColumnName2"];
                    // ...

                    dataTable.Rows.Add(row);
                }
            }
        }
    }

    return dataTable;
}
