That doesn't remove them, it just shows them.

:rolleyes: check my code again I have programmed it and then compile and after compilation it gives me output like "abc de fg hi jk". now what will you say it is removing or showing :^)

Thanks ravi it works for me.

[Henry Minute]

It has not removed them from the original string, they are still there.

you are always welcome :)

One addition to your code

string str = "abc, d.e f,g h,i. j,k";
string\[\] arr = str.Split(',', '.'); // remove all , and .
foreach (string str1 in arr)
{
    Console.Write(str1);    
}
Console.Write(str);  //<=================== Added line prints original string

What do you get when you run that? The commas and stops are still there. So, once again I say, your code does not remove those characters as the OP asked.

yes If I will use your program it will give me Original string but I did programming for removing character and then display it. as i getting OP also what this that's why he greet me for my answer. you are right in your point of view :)

Although the method will produce the results it is inefficient and causes extra work for you. The String.Replace method is more suitable for the usage you have given.

It may give the appearance of being correct but I don't believe it is what the OP asked for. You are not removing the characters from the string but simply creating an array that excludes them. Now you must recombine the array of characters back into a string to be able to use it.

yes Mark as Henry pointed me I did big mistake I've not focused my mind on that. now I am realize it was my fault. because of my program OP can only display output after removing character. its not going to remove character from string. its all happen in hurry :(

[RaviRanjanKr]

My first answer is only able to display value after removing character it will not remove for permanent. you can us Replace Method to remove . and ,

string str = "abc, d.e f,g h,i. J,k";
str = str.Replace(',',' ');
str = str.Replace('.', ' ');
Console.WriteLine(str);

Yes, and that makes me question his abilities even more.

Using the Regex class -

//Getting rid of commas ,
strComma = ",";
strReplace = string.Empty;
Regex Re = new Regex(strComma);
string newstring = Re.Replace(str,strComma,strReplace);
//Do the same for .

The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it. My latest tip/trick

You can do str = str.Split ( ... ).Join ( ... ), but it's not the right tool and inefficient.

Now that is funny. :laugh:

I must get a clever new signature for 2011.

string.Rmpty is perfectly acceptable syntax with the Scooby-Do extensions installed. :-D

Try this.

string str = "abc, d.e f,g h,i. J,k";
str = str.Replace(',', string.Empty).Replace('.', string.Empty);

[RaviRanjanKr]

I have done Minor changes in my answer

string str = "abc, d.e f,g h,i. j,k";
string[] arr = str.Split(',', '.'); // remove all , and .
str = string.Empty; // Changes here
foreach (string str1 in arr)
{
str += str1;
}
Console.WriteLine(str); //output abc de fg hi jk
