With these it helps I have a regex which checks the inputText is in valid url format or not. And working almost good:
code :
checkUrlFormat() {
    const pattern = /^(((http|https)(:\/\/))?((www).)?)[a-z0-9]+(.|[a-z0-9])+[a-z0-9]$/;

    if (pattern.test(this.inputText) || this.inputText == null) {
      return false;
    }
    return true;
  }

Convert JavaScript RegEx to C# RegEx for email validation

I think the issue was by ths following , As you are working with C#, you should be able to validate email addresses using the System.Net.Mail.MailAddress class. You can use it like this:
code :
public bool IsValidEmailAddress(string emailAddress)
{
    try
    {
        MailAddress m = new MailAddress(emailAddress);
        return true;
    }
    catch (FormatException)
    {
        return false;
    }
}

wish help you to fix your issue Two problems:
You need to escape the backslash. You need to remove the forward slashes on the beginning and end of string.
code :
var pattern = "^[A-Za-z\\s]+$";
var str = "Some Name";
pattern = new RegExp(pattern);
if(pattern.test(str))
{
    alert('valid');
}
else
{
    alert('invalid');
}

Hope this helps The C# code you've provided uses C#'s Verbatim string syntax, which doesn't require escaping of backslashes. To convert it to a normal string literal, which would be the same in C# and JavaScript, you can remove the @ symbol at the front and then escape backslashes by adding another backslash before them:
code :
 "^([0-9a-zA-Z]([-.\\w]*[0-9a-zA-Z-])*@([0-9a-zA-Z][-\\w]*[0-9a-zA-Z]\\.)+[a-zA-Z]{2,9})$"
let emailRegularExpression = new RegExp("^([0-9a-zA-Z]([-.\\w]*[0-9a-zA-Z-])*@([0-9a-zA-Z][-\\w]*[0-9a-zA-Z]\\.)+[a-zA-Z]{2,9})$");
let emailRegularExpression = /^([0-9a-zA-Z]([-.\w]*[0-9a-zA-Z-])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})$/;

This might help you The problem you're running into is that while JavaScript has a literal notation for regular expressions (this is the /.../g syntax), Java does not. In Java, you do not pass a RegEx using slashes. As you've quoted in your answer, the function signature for String.replaceAll() accepts a String as the first argument, which you are not providing.
It should work if you simply replace the slashes and global flag (replaceAll already attempts effectively a global match) with quotes to make it a String literal. Like this:
code :
String str="Customer AA: 2 TSRAs for closing the accounts. No suspicion is noted although the client is moving back to Iran.. HKD1531504.84.";
String finalStr=str.replaceAll("[^a-zA-Z0-9 \n\t,./;':<>?`\\-~!@#$%^&()_+=\"[\\]{\\}|\\*]", " ");
