c# - Retrieve all keys in a hash table into a string -


Coding language is C # 3.0 - What is the most optimal method for recovering all the hashtable keys in a different string than the delimiter?

Updates: The keys are already in the wire

Do you really mean a non-generic Hashtable ? You can use LINQ, assuming that is available to you: 

  string key = string .join (",", table.cause.lt; object & gt; (.) Select (x => x. Ostring ()) .oir ());

There may be fast approaches, but in this way I had to go for readability. Just microse-optimize when you have proved that this is an obstacle.

For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
