Select certain part in string as variable c#

I do have a string like the following "1 1/2 + 2 2/3"

Now i want the "1 1/2" as a variable, and the "2 2/开发者_如何学编程3" as a different variable. How do i fix this?

Thanks.

If you are always going to have a '+' inbetween, you could simply do:

var splitStrings = stringWithPlus.Split('+');
for (int i = 0; i < splitStrings.Length; i++) {
   splitStrings[i] = splitStrings[i].Trim();
}

edit: If you really wanted to put these two parts into two separate variables, you could do so. But it's quite unnecessary. The type of the var is going to be string[] but to get them into two variables:

var splitStrings = stringWithPlus.Split('+');
for (int i = 0; i < splitStrings.Length; i++) {
   splitStrings[i] = splitStrings[i].Trim();
}
string firstHalf = splitStrings[0];
string secondHalf = splitStrings[1];

It would be better though, to just access these strings via the array, as then you're not allocating any more memory for the same data.

If you are comfortable with Linq and want to shorten this (the above example illustrates exactly what happens) you can do the split & foreach in one line:

var splitStrings = stringWithPlus.Split('+').Select(aString => aString.Trim()).ToArray();
string firstHalf=splitStrings[0];
string secondHalf=splitStrings[1];

If this syntax is confusing, you should do some searches on Linq, and more specifically Linq to Objects.

To make it shorter I used Linq to Trim the strings. Then I converted it back to an array.

string[] parts = stringWithPlus.Split('+').Select(p => p.Trim()).ToArray();

Use them as:

parts[0], parts[1]... parts[n - 1] 

where n = parts.Length.
