This foreach is producing error.

C#

var query1 = Mystudentities.Student.Select(x=>new
{
  a=x.a,
  b=x.b,
  c=x.c
});

var query2 = Mystudentities.Engineer.Select(x=>new
{
  a=x.a,
  b=x.b,
  c=x.c
});

var inter=query1.Intersect(query2);

foreach( var x in inter)
{
    a=x.a,
    b=x.b,
    c=x.c,
    d=1,
    e=2

}

What I have tried:

C#

var query1 = Mystudentities.Student.Select(x=>new
{
  a=x.a,
  b=x.b,
  c=x.c
});

var query2 = Mystudentities.Engineer.Select(x=>new
{
  a=x.a,
  b=x.b,
  c=x.c
});

var inter=query1.intersect(query2);

foreach( var x in inter)
{
    a=x.a,
    b=x.b,
    c=x.c,
    d=1,
    e=2
}

Where exactly you get the error?

I am doubting that you should be getting the error inside the last foreach because a = x.a, b = x.b,... is invalid.

Try:


foreach( var x in inter) // this is okay.
{
    a=x.a;
    b=x.b;
    c=x.c;
    d=1; // might need to use var d = 1;
    e=2; // might need to use var e = 2;
}

You need to check more on the C# language grammar to understand how these are processed.

Hello,
Try to add

var inter=query1.intersect(query2).ToArray();

like this and then use foreach like:

foreach (var oParam in objList)
{
    Console.WriteLine(oParam.UserID);
}
