string s="00121234455" In this how to eliminate duplicates? using C# code [Resolved]

We do not require to create the List to manage the duplicate values.

We can simply do with the string variable...

string s = "Hello World";

string tempString = "";

foreach (char c in s)

{

    //Append the character, If character is already in the string append the "" value else append the character

    tempString += tempString.Contains(c.ToString()) ? "" : c.ToString(); 

}

MessageBox.Show(tempString);



//[OutPut: Helo Wrld]

You can write a small program with the loop and condition, something like

using System.Collections.Generics;



string str = "00121234455";

string temp = string.Empty;

List<string> list = new List<string>();

for (int i = 1; i <= str.length; i++)

{

    temp = str.SubString(i-1, i); // get all the characters one by one

    if (!list.Contains(temp))

    {

         list.Add(temp);

    }

}



string distinctString = list.ToString();

Hope you would be able to refine this code, if needed.

Thanks

string s="00121234455";
string sResult=string.Empty;
for(int i=0;i<s.length;i++)
{
if(!sResult.Contains(s(i).ToString()))
{
sResult += s(i).ToString();
}
}
return sResult;

I think its useful to you.
Thanks

Hey man, @T.saravanan solution might not work as "s" is not an array here. s is simply a string and you can not have an indexer in the string.

I am sure, my solution would work.

Thanks for the appreciation
One thing i would like to add in
1. T.saravanan
We are using the C# code and if you are using s(i), it is considered as function. So, in C# it should be s[i].

2. Poster
Do we require the substring for getting the Character from the string we can simply do with the character loop from the string.
like-

foreach(char c in strVariable)

{

        //Do Work here...

}

Hi Neeks,
You are right.Actually square brace is not working, so i am using normal brace.Now only i am known from your question, if we using 'i' in square brace it takes Italic model.

Thanks,
