foreach (Task03Entities.Entites item in newViewStateList)
// on above line i am getting following error message
Compiler Error Message: CS1579: foreach statement cannot operate on

解决方法
这很简单：Task03Entities.Entites不是一个集合.
你在这里初始化一个对象：
Task03Entities.Entites newViewStateList = new Task03Entities.Entites();
然后尝试迭代它,就好像它是一个集合：
foreach (Task03Entities.Entites item in newViewStateList)
{
}
我怀疑你想要的东西：
List<Task03Entities.Entites> newViewStateList = new List<Task03Entities.Entites>();
foreach (Task03Entities.Entites item in newViewStateList)
{
//code...
}
