Hello experts:
I'm having problems converting  from string to integer.
Here's my code

int AccountNumberNum = 0;  
string AccountNumberWk = '1234567890123456';   //16 bytes

AccountNumberNum = Convert.ToInt32(AccountNumberWk);


It complains that " Value was either too large or too small for an int32"
Also tried long AccountNumberNum = 0;  same result
Also tried double AccountNumberNum = 0;  same result

* System.Int32 (int)  < -2,147,483,648 to 2,147,483,647>
* System.UInt32 ( uint ) < 0 to 4,294,967,295>
* System.Int64 ( long )  <-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807>
* System.UInt64 ( ulong )< 0 to 18,446,744,073,709,551,615>

so use *long* in your task ..

long AccountNumberNum = 0;
... etc

one more thing ..
>>AccountNumberNum = Convert.ToInt32(AccountNumberWk);
when using *long* replace Convert.ToInt32 with Convert.ToInt64(....) or
like this :
AccountNumberNum = long.Parse(AccountNumberWk);

to declare int of 32 or 16 you can use Int32 or Int16



Int32 AccountNumberNum = 0;  
string AccountNumberWk = '1234567890123456';   //16 bytes

AccountNumberNum = Int32.Parse(AccountNumberWk);

Hi *t_itanium* .. your code is Wrong ..
And what is the difference between your post and the original one ??

sorry for that i should have put :

Int64 AccountNumberNum = 0;  
string AccountNumberWk = "1234567890123456";

AccountNumberNum = Int64.Parse(AccountNumberWk);

i did not realize that you explained that long and INt64 are hte same ..sorry for that..

cheers

Hey guys:

I used the following and it worked.

long AccountNumberNum = 0;
AccountNumberNum = Convert.ToInt64(AccountNumberWk);
I think t itanium came closest so he gets the points

thanks to everyone that responded

>In 4 days, the points will be re allotted to DrAske if no one has any objections.

if you think that this is fair.. i splitting the points is much fair althoug Greg mentioned that Int64 is better since it always point to 64 int..
