Examples The following example illustrates the MemberwiseClone method. It defines a ShallowCopy method that calls the MemberwiseClone method to perform a shallow copy operation on a Person object. It also defines a DeepCopy method that performs a deep copy operation on a Person object. WriteLine "Original values of p1 and p2:
The point I made about the hash table in our comment discussion above was about native compilers, not the C compiler. What threshold does the C compiler use to produce a hash table?
And btw, my anger is not you, but on people upvoting and accepting. That's with the MS. Sorry for being a bone head. In the case of Cthis is also true, but for other reasons. With a large number of strings, there is a significant performance advantage to using a switch statement, because the compiler will use a hash table to implement the jump.
With a small number of strings, the performance between the two is the same. This is because in that case the C compiler does not generate a jump table.
There is a "switch statement" MSIL instruction that when jitted will use a jump table to implement a switch statement. It only works with integer types, however this question asks about strings.
This was both wrong, and incredibly stupid on my part. Again 'IMA' pointed this out to me. I made the updates here because it's the highest rated post, and the accepted answer. If you get a chance, please up vote 'ima''s post.A Dictionary class is a data structure that represents a collection of keys and values pair of data.
The key is identical in a key-value pair and it can have at most one value in the dictionary, but a value can be associated with many different keys.
Nov 29, · Use Write when you want to write some text. Use WriteLine when you want to write some text and start a new line. Using Write you can continue writing on the same line with subsequent Write(s).
Represents a collection of keys and values. As long as an object is used as a key in the Dictionary, it must not change in any way that affects its hash grupobittia.com key in a Dictionary must be unique according to the dictionary's equality comparer.
A key cannot be null, but a value can be, if the value type TValue is a . Difference between Equality Operator (==) and Equals() Method in C#. Answer: Both the == Operator and the Equals() method are used to compare two value type data items or reference type data items.
Another advantage of HashSet is that you get nifty set operations (like Union, Intersection, Set Difference and Symmetric Set Difference) that are not exposed by Dictionary.
If the keys need to be maintained in order (a la SortedDictionary), the proper Collection is SortedSet. Looks like most of the difference between grupobittia.comlLines() and the streamreader is in how the reading is being performed.
I wrote myself a custom reader for the linq version and gained almost a second.
