VB.NET App: How to convert Unicode String to Integer?

[vaskar]

I have got one problem in VB.NET 2005 using unicode
I want to add two numbers in vb.net 2005 through UNICODE
I didn't know how to convert UNICODE string to integer.

I hope you can solve my problem

Can you post what you have tried so far.

[Plater]

int.parse() has overloads that might be able to help you with a unicode string?

I want to add two NepaliUnicode number as
[code=vbnet]
Dim a as string=me.textb ox1.text
dim b as string=me.textb ox2.text
dim c as integer=val(a+b )
[/code]
Above statement throw exception "Input string was not in correct format" Format Exception was unhandled

I have done above coding through this also:
[code=vbnet]
Dim a as string=Integer. Parse(me.textbo x1.text)
[/code]
Above statement throw exception "Input string was not in correct format" Format Exception was unhandled

if you have any idea to convert string to integer but the string is in numeric type unicode.

I could not find solution for my problem so give me best idea.

try this way
[code=vbnet]
Dim myBytes As Byte() = System.Text.Enc oding.Unicode.G etBytes(textbox 1.text)

Dim myChars as Char() = System.Text.Enc oding.Unicode.G etChars(myBytes )
Dim myString as String = New String(myChars)[/code]


Then convert the string to integer

try this way
Dim myBytes As Byte() = System.Text.Enc oding.Unicode.G etBytes(textbox 1.text)

Dim myChars as Char() = System.Text.Enc oding.Unicode.G etChars(myBytes )
Dim myString as String = New String(myChars)


Then convert the string to integer

Thank You mzmishra

I had try as per you say.
when I convert MyString to integer Exception arises
that is "Input String was not in correct format" but the string which I press is string representation of numeric type of unicode that is 1 in US-eng and "१" in Nepali Unicode.

my line of code is

Dim myNum as Integer =Integer.parse( myString)

If you have any idea. I will be thanks for your help.

[mzmishra]

Hmm.
Not sure then.Probably someone else can give some idea

[Plater]

If I had to guess, I would think you would need to use the overloads for int.parse() that use the NumberFormatInf o object.
It can be assigned a culture.
You may also need to do things like allow decimal and thousands seperators.

What is the string you are trying to conver to integer?
Even as a unicode string, they still need to represent numbers, so random symbols won't work.

int.parse("123j jk"); will throw the same error, regardless of being a unicode or ascii string.
