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?

Can you post what you have tried so far.

I want to add two NepaliUnicode number as

Dim a as string=me.textbox1.text
dim b as string=me.textbox2.text
dim c as integer=val(a+b)
 

Above statement throw exception "Input string was not in correct format" Format Exception was unhandled

I have done above coding through this also:

Dim a as string=Integer.Parse(me.textbox1.text)
 

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.

Hi Plater

[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.

try this way

Dim myBytes As Byte() = System.Text.Encoding.Unicode.GetBytes(textbox1.text)
 
Dim myChars as Char() = System.Text.Encoding.Unicode.GetChars(myBytes)
        Dim myString as String = New String(myChars)

Then convert the string to integer

[vaskar]

try this way
Dim myBytes As Byte() = System.Text.Encoding.Unicode.GetBytes(textbox1.tex t)

Dim myChars as Char() = System.Text.Encoding.Unicode.GetChars(myBytes)
Dim myString as String = New String(myChars)


Then convert the string to integer

Thank You mzmishra
I will try it.

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 NumberFormatInfo 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("123jjk"); will throw the same error, regardless of being a unicode or ascii string.
