ScalarFieldName

RSS

If your method returns a dictionary of scalar values, you will have to specify the name or index of the field used to populate the scalar list. The ScalarFieldName attribute allows you to do that.

ScalarFieldName.cs

using System;
using System.Collections.Generic;

using NUnit.Framework;

using BLToolkit.DataAccess;

namespace HowTo.DataAccess
{
    [TestFixture]
    public class ScalarFieldName
    {
        public abstract class TestAccessor : DataAccessor
        {
            [SqlQuery("SELECT PersonID, FirstName FROM Person")]
            [Index("PersonID")]
            [ScalarFieldName("FirstName")]
            public abstract Dictionary<int, string> GetPersonNameDictionary();
        }

        [Test]
        public void Test()
        {
            TestAccessor pa = DataAccessor.CreateInstance<TestAccessor>();

            IDictionary<int, string> dic = pa.GetPersonNameDictionary();

            Assert.AreEqual("John", dic[1]);
        }
    }
}
