Check string to see if it DOES NOT start with "x" Check string to see if it DOES NOT start with "x"

[nmjvk]

Dear UiPathers

Is it possible to check if something DOES NOT start with something else?
An example could be, I want to test if a string DOES NOT start with the letter “x”?

Is there an efficient way to do that?

HI @nmjvk

Can you share the sample input string and expected output?

@nmjvk,

Try with this,

Not (yourStringVariable.StartsWith("yourStringToCheck", StringComparison.OrdinalIgnoreCase))

[Gokul001 (Gokul Balaji)]

HI @nmjvk

You can try with Regex Expression

System.Text.RegularExpressions.Regex.IsMatch(YourInputString,"^x|^X")

Yes,
Try

Not string_name.startswith("x")

[ppr (Peter Preuss)]

Not YourStringVar.Trim().StartsWith("x")
Or (harmonized)
Not YourStringVar.Trim().ToUpperStartsWith("X")

Here I have an if condition where I am looping through all of my columns. I want to say "if the column DOES NOT START with (“P-enhedens”)

I get this error when trying to do your solution

You have duplicate variable in the panel delete any one of them and check it @nmjvk

Here I have an if condition where I am looping through all of my columns. I want to say "if the column DOES NOT START with (“P-enhedens”)

For each Activity: item in dt.Columns.Cast(Of DataColumn).Select(Function (x) x.ColumnName)
TypeArgument: String

If Activity: Not item.Trim().StartsWith(“P-enhedens”) - when it should be negated, otherwise ommit the Not
Then: Remove DataColumn use Colname: item
Else: do other things

Kindly note: we are looping over the names because of would we loop over the columns and delete a column we would get a collection modified exception

As an alternate we can alos loop over dt.Clone.Columns then we can delete columns from original datatable without collection modified exception

I keep getting the same error

I come from a programming background, I know most langauges support negation such as “Not(something)” which works perfect, it’s simple and easy to read. Does UiPath offer the same?

I come from a programming background,

This we can never know when we do read a question.Perfect with all given samples you can finalize and close the topic

Your variable is not initialized properly. Can you check the variable Ft2 and Counter?

[nmjvk]

That’s it, I did not properly declare my variable. Solutions given by @sarathi125 and @ronconi works the best for me. I will accept @sarathi125 answer since he was the first. Thanks!
