Str3=“def”

Hi @vnsatyasunil ,

Do you want to get the name of the variable that matches the condition ?

If so, we would suggest to use a Dictionary approach for storing the values so that using the value, we could be able to get the Key name.

I’m not so sure about fetching the variable names based on the value provided.

Let us know more details about your use case which would help us understand the requirement more and thus provide/suggest a better solution.

Hi @vnsatyasunil,

string.isNullorwhitespace(dic[key].Tostring())
string.isNullorEmpty(dic[key].Tostring())

You can use either one of the above code.

Thanks

For this expression continuation expected is coming.
In the same expression can we pass 4 variable names and get which variable has empty value
