yah like this in if condition
Char.IsUpper(string yourstring, int index)
where index is the possition where you want to check whether it has upper case character or not

@AshwinS2 Hi, this condition gives true only if all the characters in the string is uppercase.
i need if any one character is upper case it should give true value.

Hi @soorya_prasad

You can use palaniappan query or

Use string var.touppervariant(index position).contains(“A”)

@Palaniyappan I need to check the whole string at once. I dont want to check the particular index. if my string contains any uppercase character it should return true value.

@soorya_prasad as mentioned by @Palaniyappan and @AshwinS2 add one more step for your string . Create a character Array of your string then apply this in for each loop Char.IsUpper(CharacterArray[i]) and increment the counter then you will get the count, if count greater than 0 then yes else No.

@soorya_prasad

Use below code to check Upper case in String it will return number how many upper case character …if it return 0 then no upper case in the string

system.Text.RegularExpressions.Regex.Matches(yourInputString,“[A-Z]”).Count.ToString

@soorya_prasad you can use as shown below

assign v1 = “uIpAth”
assign v1 = System.Text.RegularExpressions.Regex.IsMatch(v1,“[A-Z]”)

Now this will give boolean result that is true

Fine
we can use REGEX

out_count = System.Text.RegularExpressions.Regex.Matches(yourInputString,“[A-Z]”).Count.ToString
to know which characters

then simiply

out_matches = System.Text.RegularExpressions.Regex.Matches(yourInputString,“[A-Z]”)
Where out_matches is a ienumerable of string type
–now use a for each loop and pass the above variable
–inside the loop use write line and mention as item.tostring which will show us the character in caps

Cheers @soorya_prasad
