facing issues to know how do we remove characters from a String?
Consider the following example for mobile number cleanup, Take a textbox on the form
Rename it to ="TxtMobile"
Add a label and rename it to"LblResult"
Add a label and rename it to "CmdSubmit"
Declare a public string
Public Mobile As String
Under "CmdSubmit" click write the following code:
Protected Sub CmdSubmit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles CmdSubmit.Click
If Not TxtMobile.Text = "" Then
LblResult.Text = ""
Mobile = TxtMobile.Text
Lblresult.Text = Mobile
Label1.Text = "Enter Mobile Number with some characters"
The above code assigns textbox value to public string we have declare above and passes it to sub CheckforChars(), Then the results are shown in Lblrsult.
Aslo write two small functions to remove characters from string of numeric
The below functions removes all the digits or numeric values from a string and stores all the chacters
Public Shared Function RemoveDigits(ByVal key As String) As String
Return Regex.Replace(key, "\d", "")
The Mobile number with characters is passed through the above function in the below sub and returned value from the above function is stored in a string called Value1
The characters present in Mobile number are replaced with nothing, you can also use .remove here instead of replace
Private Sub CheckforChars()
Dim value1 As String = RemoveDigits(Mobile)
Mobile = Mobile.Replace(value1, "")
