Hi everyone,

I have a data in the excel with the column A, where the values may start with alphabets or numerical.
How to check the starting character is alphabet or numerical

For example

If it starts with alphabet i need to enter the data in text field, if its a number the we need to enter in exam Regno field

Please le me know if anyone has solution.

Another apporach is to work with Regex and group names:

where we can formulate following:

new Regex("(?<isDigit>^\d)|(?<isLetter>^[A-Za-z])").Match("1234").Groups.Cast(Of Group).Skip(1).Where(Function (g) g.Success).Select(Function (g).Name).toArray

same within the Query syntax

arrValidation =

(From g in new Regex("(?<isDigit>^\d)|(?<isLetter>^[A-Za-z])").Match("1234").Groups.Cast(Of Group).Skip(1)
Where  g.Success
Select n = g.Name).toArray

which can be optimized and dynamized by using variables

Hello.

You can use the function “first()”, “IsNumeric()”, “IsLetter” or “IsDigit”.

Example:

Char.IsDigit(“text”.First())

The result is always true or false.
