Question

I am using LINQ-to-Entities and here is my query

public void SomeFunction(string searchField)
{
var data = from a in dx.SomeTable where         
                a.SomeProperty="270"
                select a;
.
.
.

}

Now if I had to use the value of the parameter “searchField” as the property to be selected in the where clause then how do I do it ?

i.e I want to assign the value of the parameter “searchField” to the property I am checking in the where clause.

So … the value of “SomeProperty” in a.SomeProperty must be the value of “searchField”. How to do this ?

PS :

I dont want a.SomeProperty=searchField.

What I want is “SomeProperty” itself to be replaced by the value of “searchField” and then , this has to be checked to see if its equal to 270.
