示例1: ExecuteEntity
public void ExecuteEntity()
{
string sql = "SELECT 1 AS IntColumn, 'FizzBuzz' AS StringColumn WHERE @Fizz = 1";
var dict = new Dictionary<string, object> {{"@Fizz", 1}};
// Examples
using (var conn = new SqlConnection(My.Config.ConnectionString.UnitTest.ConnectionString))
{
conn.Open();
var entity = conn.ExecuteEntity<TestObject>(sql, dict.ToDbParameters(conn));
// Unit Test
Assert.AreEqual(1, entity.IntColumn);
Assert.AreEqual("FizzBuzz", entity.StringColumn);
Assert.AreEqual(-1, entity.IntColumnNotExists);
