示例1: ExecuteEntities
public void ExecuteEntities()
{
string sql = "SELECT 1 AS IntColumn, 'FizzBuzz' AS StringColumn UNION SELECT 2, 'BuzzBuzz' WHERE @Fizz = 1";
var dict = new Dictionary<string, object> {{"@Fizz", 1}};
// Examples
using (var conn = new SqlConnection(My.Config.ConnectionString.UnitTest.ConnectionString))
{
conn.Open();
List<TestObject> list = conn.ExecuteEntities<TestObject>(sql, dict.ToSqlParameters()).ToList();
// Unit Test
Assert.AreEqual(1, list[0].IntColumn);
Assert.AreEqual("FizzBuzz", list[0].StringColumn);
Assert.AreEqual(2, list[1].IntColumn);
Assert.AreEqual("BuzzBuzz", list[1].StringColumn);
Assert.AreEqual(-1, list[0].IntColumnNotExists);
