Problems with Console.Read()

[ria_h85]

Hi,

I am stuck with this very basic problem that I am unable to resolve. Here is a piece of code that I am working on:

Module Module1
Sub Main()
Console.Write("Enter Age, Name Salary: ")
Age = Console.Read()
FirstName = Console.Read()
Salary = Console.ReadLine()
Console.WriteLine(Age & " " & FirstName & " " & Salary)
End Sub
End Module

At the command prompt I enter the following values

20 Ann 20000

and it gives me an InvalidCastException

Could you explain what kind of input would be suitable to make this run???

I think Console.Read just reads one single character so when you type 20 and expect that to go into the Age variable, its actually only the 2 that goes in and then 0 probably ends up in the FirstName variable.

Having said that, that shouldnt cause an InvalidCastException. Are you actually declaring Age, FirstName and Salary anywhere?

Thanks for replying...

yes....sorry i forgot to mention....I declare them as Integer, String and Double respectively in the beginning of the code!

My understanding is that Console.Read() reads characters
up to the first whitespace character, such as a space or tab.

But as per the output I think your explanation makes sense...

Have a read of the MSDN documentation on what it does exactly: http://msdn.microsoft.com/en-us/libr...sole.read.aspx

I would just use Console.ReadLine all of the time if I were you
