How to keep character " as a part of string - vb.net

Question

I am new to VB
Dim myStr As String
myStr = "00101"
Dim Rat As String
Rat = "0"
I wish to build new string that will contain myStr but with character "
I mean that final string FinStr should look like this:
FinStr = "AT+COPS=1,2,"00102",0" //where 0 is RAT
So how to keep the character " ?
What is the best function to build string?
Can I do:
FinStr = "AT+COPS=1,2,\"" & myStr & "\"," & Rat
Thanks

There are also a set of Control Characters available:
Try
Dim myStr As String = ControlChars.Quote & "00101" & ControlChars.Quote
I find this much more readable than multiple quotes stacked together.
If I understand your expected result, I would think something like this is what you want:
Dim myStr As String
myStr = ControlChars.Quote & "00101" & ControlChars.Quote
Dim Rat As String
Rat = "0"
FinStr = "AT+COPS=1,2," & myStr & "," & Rat

There are two ways to put double quotes in your string. The first option is to double the amount of quotes:
Dim MyString As String = """Hello, I am a string!"""
Notice that there are three quotes in the beginning and end of the above string. This is because the very first and the very last one represents the beginning and end of a string.
In order to put a quote in the middle of the string you only have to type two quotes "". Example: "He stopped for a moment, and yelled: ""I like bananas!"" "
The second option is to use the Chr() function:
Dim MyString As String = Chr(34) & "Hello, I am a string!" & Chr(34)
Chr(34) represents the quotation mark character.
