I want to separate a sub string from a string array where my start Char (") and my ending Char (").

My Code:

C#

int count = 0;
string[] arr1 = new string[reply.Length-20];
foreach (string item in list)
               {
                   arr1[count] = item.Split(new Char[] { '"','"' });
                   Console.WriteLine(item);
                   count = count + 1;
               }

Please help me to separate a substring from a string whit start char to end char.
Thanks in advance.

What I have tried:

arr1[count] = item.Split(new Char[] { '"','"' });

Split doesn't work like that!
Possibly what you want is:

C#

int count = 0;
foreach (string item in list)
    {
    string[] arr1 = item.Split(new char[] {'"'}, StringSplitOptions.RemoveEmptyEntries);
    foreach (string s in arr1)
        {
        Console.WriteLine(s);
        count = count + 1;
        }
    }

The issue is not really clear. However, String.split returns an array, so you cannot store the result in arr1[count], since that is a string reference. not a string[] reference. Similarly why are you printing item in the next line, rather that some split data? You probably need to do something like:

C#

foreach (string item in list)
{
    string[] splits = item.Split(new Char[] { '"','"' });
// do something with the split subitems
}

It is not clear what you want to do with this code, but it can be simplified.

C#

int count = 0;
string[] arr1 = new string[reply.Length-20];
foreach (string item in list)
    {
       arr1[count] = item.Split(new Char[] { '"','"' });
       Console.WriteLine(item);
       count = count + 1;
    }

You do nothing with the variable count

try this, if you need to get the value between two double quotes but best way to do this is using Regex [^]

C#

string some = " start \"Hello world \" end "; // start "hello world" end
          var items = some.Split('"');
          if (items.Length > 2)
          {
              string value = items[1]; // Hello world
          }

Where do you use regex in your solution?

Karthik_Mahalingam 11-Jun-16 10:38am

Hi George,
Its a suggestion to the OP, but i have just modified the code in the way he was trying to achieve the need.

George Jonsson 11-Jun-16 10:51am

It just looks a bit odd to suggest using regex and then the code presented has nothing to do with that.

Karthik_Mahalingam 11-Jun-16 11:16am

hmm, i understand.Lets see what the Op needs exactly.

George Jonsson · Answer 5 · 2016-06-11T04:47:00

It can be done by using a regular expression.

C#

// The expression will find any word between double quotes
Regex expr = new Regex("\"(?<word>[^"]+)\"");

string input = "There are two \"double\" quoted words in this \"string\".";
foreach (Match m in expr.Matches(input))
{
    // Using a named group makes it clear how to extract the values.
    Console.WriteLine(m.Groups["word"].Value;
}
