Creates a FrozenDictionary<TKey,TValue> from an IEnumerable<T> according to specified key selector function. ToFrozenDictionary<TSource,TKey,TElement>(IEnumerable<TSource>, Func<TSource,TKey>, Func<TSource,TElement>, IEqualityComparer<TKey>) Creates a FrozenDictionary<TKey,TValue> from an ...
Since the Dictionary<TKey,TValue> is a collection of keys and values, the element type is not the type of the key or the type of the value. Instead, the element type is a KeyValuePair<TKey,TValue> of the key type and the value type. For example:...
This context provides the connection and metadata information that is required to compose and execute the query. An object query is executed in the following scenarios:When it is acted upon, such as during a foreach (C#) or For Each (Visual Basic) enumeration. When it is assigned to fill ...

You can apply this method to a sequence of arbitrary values if you provide a function, selector, that projects the members of source into a numeric type, specifically Nullable<Int64> in C# or Nullable(Of Int64) in Visual Basic. In Visual Basic query expression syntax, an Aggr...
