Computes the sum of the sequence of nullable Double values that are obtained by invoking a transform function on each element of the input sequence. From a performance standpoint, these methods should be used with caution. The index of each source element is used in the intermediate projected form of that element. This list must be modifiable, but need not be resizable. the sort that commonly exist for arrays). It traverses the list from the beginning, passing each element in turn to the EndsWithSaurus method. Catalog adds the idea of alphabetical or other orderly arrangement, and, often, descriptive particulars and details: a library catalog. Produces the set intersection of two sequences by using the specified IEqualityComparer to compare values. The List interface provides two methods to efficiently insert and remove multiple elements at an arbitrary point in the list. Gets a value indicating whether the IList is read-only.

Listmaker is where you can create lists on any topic or subject. That means a list element of a List object does not have to be boxed before the element can be used, and after about 500 list elements are created, the memory saved by not boxing list elements is greater than the memory used to generate the class implementation. The list is populated with four strings, and the AsReadOnly method is used to get a read-only IList generic interface implementation that wraps the original list. However, if a value type is used for type T, you need to consider implementation and boxing issues. Removes the element at the specified position in this list (optional if it is present (optional operation).
