示例1: ToString
[Test] public new void ToString()
{
DataSet ds = new DataSet();
DataTable dtChild = DataProvider.CreateChildDataTable();
DataTable dtParent = DataProvider.CreateParentDataTable();
ds.Tables.Add(dtParent);
ds.Tables.Add(dtChild);
DataRelation dRel;
dRel = new DataRelation(null,dtParent.Columns[0],dtChild.Columns[0]);
// ToString 1
Assert.AreEqual(string.Empty , dRel.ToString() , "DR10");
ds.Relations.Add(dRel);
// ToString 2
Assert.AreEqual("Relation1", dRel.ToString() , "DR11");
dRel.RelationName = "myRelation";
// ToString 3
Assert.AreEqual("myRelation", dRel.ToString() , "DR12");
}示例2: run
//Activate This Construntor to log All To Standard output

//BY DEFAULT LOGGING IS DONE TO THE STANDARD OUTPUT ONLY FOR FAILURES
