C#

string schoollist ='102','11','23','34'
string[] SchoolListArr = schoollist.Split(',');

for (int i = 0; i < SchoolListArr.Length; i++)
{
    //Console.WriteLine("The school List:" + SchoolListArr[i]);

 //   String s = null;

    String[] schools = new String[100];

    schools[i] = SchoolListArr[i];

    Console.WriteLine("The school List:" + schools[i]);

}
Console.ReadLine();

// now my question is how do I strip ( ' ') from the  string so that I have 

102
11
// instead of 
'102'
'11'

// thank you

For stripping spaces (' ') you Trim the text.

Solution 1

For starters, the code you have put in your question will not compile.
string schoollist ='102','11','23','34' would need to be string schoollist ="'102','11','23','34'";

In order to replace values in a string, you could very simply use the string.Replace() method.
schoollist = schoollist.Replace("\'", string.Empty);

Solution 2

Try:

C#

string schoollist = "'102','11','23','34'";
schoollist = schoollist.Replace("'", ""); // <== add this line
string[] SchoolListArr = schoollist.Split(',');

You also need to surround your schoollist string with quotes and add a semicolon at the end of the line, otherwise it won't compile.

Hope this helps.

Solution 3

This is one way you could do it, using string.Trim(params char[])

Console.WriteLine("The school List:" + schools[i].Trim(char.Parse("'")));

It seems that your real question is, "How do I convert a string value into a numeric value?"

Inside your loop, the only line you need is

C#

schools[i] = Convert.ToInt32(SchoolListArr[i]);

You can use a cast instead, if you want; personally, I try to use .Net methods rather than language-specific syntax.

Move the declaration of schools to before the loop -- there is no need to keep recreating it -- make it an array of int and initialize it to have SchoolListArr.Length elements. I believe the writeline should be after the loop.
