c# - Improve Code: Compare 2 list of elements -


Sorry for the newbie question, but, I am new to programming ..

I check I do not already have more than one element in TypeA in listOfDifferentTypes . I have followed the code: 

  Public Zero check type (object param) {if (the absolute is TypeA) {int i = 0; TypeA paramToCheck = (TypeA) Ultimate; Foreign currency (different pariagag, different type in the list) {If (Parab is type A) {var paramInList = (TypeA) paramB; If (paramToCheck.ID == paramInList.ID) {i ++; }}} If (i> 1) {paramToCheck.m_Error = "Error Text"; }}}

I think this is not a very clean solution, can this code be improved / customized?

You can use LINQ for this :) It would look great: 

  // Check for string - Replace & lt; String & gt; With & lt; Some type & gt; Private bowl for more types on other types (list & lt; objects & gt; different types) {type different types. Type & lt; String & gt; (). Calculate ()> 1; }

Usage: 

  list & lt; Object & gt; List different types = new list & lt; Object & gt; {"String", 13, 52, "string", 54.3f}; Var res = moreThanOne (list different types);

I see that if you also check for any type of identity, then try it:

To do what your code is doing Updated

Updated: has been replaced. () with. (1). Some () will be closed if it is more than 1) 

  Private zero check-type (Object param, list & lieutenant; object & Gt; different types) {var paramToCheck = Ultimate in TypeA; If return (paramToCheck == empty); Var res = different Types.OfType & lt; TypeA & gt; (). Where (t = & gt; tid == paramToCheck.id). Skip (1). anyone (); If (res) paramToCheck.m_Error = "Error Text"; }

As I have done, you can change it: 

  if (the absolute typeA) {TypeA paramToCheck = (TypeA) param; ... something with

with: 

  as TypeA paramToCheck = param TypeA; // Return is not returned if not tyai (absolute == blank); ... do something

this is a little bit faster :)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? 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....
