How to remove special character from string

Pinku

Title='U.S. History-part 1'
Dim cleanString As String = Regex.Replace(title, "[^a-zA-Z 0-9-/-]", "")
The result I am getting is : US History-part 1 but I need like : US History part 1 . So if there is hiffen that should also replace with blank space.
The title data is dynamic . I have just given a example.
Below is some example of what it should be from left to right.
U.S. History-part 1 => US History part 1
U.S. History.part.1 => US History part 1
U.S- History : part 1 => US History part 1

To remove special characters from string, you can modify the regular expression to remove not just special characters, but also replace hyphens and other unwanted characters like periods, colons, etc. with a blank space.

Check the below code:
```
Imports System.Text.RegularExpressions

Dim title As String = "U.S. History-part 1"
Dim cleanString As String = Regex.Replace(title, "[^a-zA-Z0-9\s]", " ")
cleanString = Regex.Replace(cleanString, "\s+", " ")
cleanString = cleanString.Trim()

Console.WriteLine(cleanString)
```

Hello Pinku ,

To clean up a string in Visual Basic .NET and remove special characters while replacing hyphens and periods with spaces, you can use the following code:
```
Imports System.Text.RegularExpressions

Dim title As String = "U.S. History-part 1"
Dim cleanString As String = Regex.Replace(Regex.Replace(Regex.Replace(title, "[^a-zA-Z0-9.-]", " "), "[.-]", " "), "\s+", " ").Trim()

Console.WriteLine(cleanString) 
```
In this code, the first Regex.Replace removes unwanted special characters. The second Regex.Replace replaces hyphens and periods with spaces. The third Regex.Replace consolidates any multiple spaces into a single space, and Trim() ensures there are no leading or trailing spaces. This method effectively cleans up the string to meet your requirements.

Thanks!
