Once upon a time there was a set, how to find a element of a set

Question

I would like to do something like

if character in ('E', '^', ',','.') //capital E, a dakje, a comma and a dot
{
//do something
}

I thought there was a set, or a enum and also a "in" - keyword.
But I can't find it anymore.

What is the correct way to find a member of a set

Answer 1

You could convert the string to a char array and then use the Contains function.

to Contains: https://stackoverflow.com/questions/13257458/check-if-a-value-is-in-an-array-c

to char array: https://msdn.microsoft.com/en-us/library/2c7h58e5(v=vs.110).aspx

finally for more complex constructs like "keyword" in "ksadkeywordsads" you can always use RegEx

Answer 2

Oeps. Then I have a memory flash back from when I was programming in Delphi (Pascal). Which still is a good language.

Do you know how to do it in C# ? ;-)

Answer 3

Dont worry, we are not talking about get; set;
We are talking about a group of variables.

Answer 4

I want to analyze a string for certain characters like

E capital E
^ dakje ( I do not the english word)
, comma
. dot

If they are in the string, I want to do something

Answer 5

@ace : yes that is what I want to do.

Answer 6

Thank you all.

I used the array and contains method. From the stackoverflow link from Chrizzhigh.

No it works.

static bool IsAString(string userInput)
{
bool result = true;
char[] ExceptionArray = new char[] {'E', '^', '.', ','};

foreach (char ch in userInput)
{
if (ExceptionArray.Contains(ch))
{
return false;
}

}
return true;
}
