Solution 6 is good. It might try following,

C#

static void Main(string[] args)
{
    string str = "Today, is a good day. Tomorrow, will rain!";
    var result = new String(str.Where(ch => !Char.IsPunctuation(ch) && !Char.IsWhiteSpace(ch)).ToArray());
    Console.WriteLine(result);
}

Solution 3

You may either call repeatedly the String.Replace(Char, Char) method or iterating on string characters generating a new string containing only the wanted ones.

You may also follow this[^] approach.

Try this code.

C#

public string RemoveChars(string str)
    {
        string[] chars = new string[]{",",".","/","!","@","#","$","%","^","&","*","'","\"",";","-","_","(",")",":","|","[","]"};
        for(int i = 0; i< chars.Length; i++ )
        {
            if(str.Contains(chars[i]))
            {
                str = str.Replace(chars[i],"");
            }
        }
        return str;
    }

Solution 4

Hi,

You can use string function Replace to remove these characters:

C#

string str="Today, is a good day. Tomorrow, will rain!";
str = str.Replace(",", "");
str = str.Replace(".", "");
str = str.Replace("!", "");
str = str.Replace(" ", "");

Solution 6

I think the Replace method of System.Text.RegularExpressions.Regex class can be used for this purpose

C#

string text = "Today, is     a good day. Tomorrow, will rain!";
//Remove punctuation characters and spaces
string textSansPunctuationSpace = System.Text.RegularExpressions.Regex.Replace(text,@"\p{P}|\s+","", RegexOptions.CultureInvariant);
Console.WriteLine (replacedText);
//Output:
//TodayisagooddayTomorrowwillrain
