Using lambda with dictionaries

Question

I am trying to use LINQ to extract some data from a dictionary.

var testDict = new Dictionary<int, string>(); testDict.Add(1, "Apple"); testDict.Add(2, "Cherry"); var q1 = from obj in testDict.Values.Where(p => p == "Apple"); var q2 = from obj in testDict.Where(p => p.Value == "Apple"); 

The above lines, q1 and q2, lead to a compiler error.

 error CS0742: A query body must end with a select clause or a group clause 

How do I use LINQ to find values ​​in a dictionary?

Thanks,

Rick

Answer 1

Or

 var q1 = from obj in testDict.Values where obj == "Apple" select obj; 

or

 var q1 = testDict.Where(p => p.Value == "Apple"); 

Answer 2

you have additional "from obj in" in your statements that are not needed. Either remove this, or change .Where to linq query syntax instead of method syntax.

 var q1 = from obj in testDict.Values where obj.Value == "Apple" select obj; var q2 = testDict .Where(p => p.Value == "Apple");
