2. 使用方法
public IEnumerable<T> SqlQuery<T>(string sql, IDbDataParameter[] parameters)
{
ValidateOperator.Begin()
.NotNullOrEmpty(sql, "Sql语句")
.NotNull(parameters, "sql对应参数");
var dataParameters = CreateParameter(parameters);
return CurrentConnection.Query<T>(sql, dataParameters, CurrentTransaction);
}
