I get string input like: 1+2*5+sin100-2 and In order to calculate it I need to make array that will look like:
1,+,2,*,5,+,sin,100,-,2
Is there easy solution to do this problem?
Currently I am doing it with loop on all the chars in the string but I want to know if c# offer easiest solution to this problem.
I found easy solution. You could just write it instead of complain that there is no code in the question.
string expression;//my calculator expression
string[] operators;//array that contains both unary and binary operators.
for(int i=0;i<operators.length;i++)
{
expression = expression.replace(operators[i]," "+operators[i]+ " ");
}
string[] Values= expression.split(" ");

I want to remove some string from regex in c#.
I have a string
000603ABC140702-005051-I-FILL200-NNYYNY180319-142110-A2002.zip
From this I want to remove those strings
140702
142110
And I want a result as
000603ABC-005051-I-FILL200-NNYYNY180319--A2002.zip
How can I do that in regex?
You can use the Regex.Replace method (https://msdn.microsoft.com/en-us/library/xwewhkd1(v=vs.110).aspx).
var regex = new Regex("(140702)|(142110)");
var result = regex.Replace("000603ABC140702-005051-I-FILL200-NNYYNY180319-142110-A2002.zip", "");
Although, as already stated by #CompuChip, String.Replace would probably be more efficient in this case. There's a discussion of various methods of replacing substrings and their efficiency at https://blogs.msdn.microsoft.com/debuggingtoolbox/2008/04/02/comparing-regex-replace-string-replace-and-stringbuilder-replace-which-has-better-performance/.

I need a c# function that takes a string:
Input: "str1__value__xyz__str4__"
I want to convert it to an array (or list) of string
Output: string[] output = { str1, value, xyz, str4}
I think we can use Linq or a regular expression.
Input.Split(new string[] { "__" }, StringSplitOptions.None);

I have the following:
The __animal__ jumped over the __object__
I'd like to write a concise method in C# that returns animal and object. How can this be done without RegEx? A dirty solution would be to iterate through the characters one by one until we find a __ and then build a string until we find the closing __ - but I'm looking for a more elegant approach.
You are going to have to iterate in some form - if you don't want to use regex.
string text = "The __animal__ jumped over the __object__";
List<string> words = text.Split(' ').ToList();
words = words.Where(x => x.StartsWith("__") && x.EndsWith("__")).ToList();
You can use extensions of IEnumerable.to search, like above. but the framework is technically iterating.

I am new to RegEx and looking for a solution to this condition. I am writing my code in C# and don't want to use any STRING functions.
Below is a sample string that I get:
610WBDFGFGM0122544
Now the condition I need to check is,
If string starts with "6" && 6th character is "D"
Can anyone tell me how to write RegEx for the above condition?
You can use this regex:
^6.{4}D
Here, ^ is the start of the string, .{4} means any four characters.

Which is the best way I can compare two C# string variables containing comma separated values and find the difference?
The scenario is like.
string variable1 = "AAA, BBB, CCC, DDD";
string variable2 = "AAA, CCC, DDD, EEE";
And I need the result like "BBB" (the value which is present in variable2 but not in variable1.
Thanks
Use Except:-
var result = variable1.Split(new char[] {','})
.Except(variable2.Split(new char[] {','})).ToArray();
