## Examples
The following code example shows how to use the <xref:System.Collections.Generic.Dictionary%602.%23ctor%28System.Collections.Generic.IEqualityComparer%7B%600%7D%29> constructor to initialize a <xref:System.Collections.Generic.Dictionary%602> with sorted content from another dictionary. The code example creates a <xref:System.Collections.Generic.SortedDictionary%602> and populates it with data in random order, then passes the <xref:System.Collections.Generic.SortedDictionary%602> to the <xref:System.Collections.Generic.Dictionary%602.%23ctor%28System.Collections.Generic.IEqualityComparer%7B%600%7D%29> constructor, creating a <xref:System.Collections.Generic.Dictionary%602> that is sorted. This is useful if you need to build a sorted dictionary that at some point becomes static; copying the data from a <xref:System.Collections.Generic.SortedDictionary%602> to a <xref:System.Collections.Generic.Dictionary%602> improves retrieval speed.

## Examples
The following code example creates a <xref:System.Collections.Generic.Dictionary%602> with a case-insensitive equality comparer for the current culture. The example adds four elements, some with lower-case keys and some with upper-case keys. The example then attempts to add an element with a key that differs from an existing key only by case, catches the resulting exception, and displays an error message. Finally, the example displays the elements in the dictionary.

## Examples
The following example demonstrates all three overloads of the <xref:System.Collections.Generic.List%601.LastIndexOf%2A> method. A <xref:System.Collections.Generic.List%601> of strings is created, with one entry that appears twice, at index location 0 and index location 5. The <xref:System.Collections.Generic.List%601.LastIndexOf%28%600%29> method overload searches the entire list from the end, and finds the second occurrence of the string. The <xref:System.Collections.Generic.List%601.LastIndexOf%28%600%2CSystem.Int32%29> method overload is used to search the list backward beginning with index location 3 and continuing to the beginning of the list, so it finds the first occurrence of the string in the list. Finally, the <xref:System.Collections.Generic.List%601.LastIndexOf%28%600%2CSystem.Int32%2CSystem.Int32%29> method overload is used to search a range of four entries, beginning at index location 4 and extending backward (that is, it searches the items at locations 4, 3, 2, and 1); this search returns -1 because there are no instances of the search string in that range.
