Check if already exists in list/table

[awzse00]

Hi guys i'm trying to figure out how this snippet works, is it still up to date? Because i'm trying for the last 2 hours to get it running.
Basically i need to check if a Dealer is in my list already or not. If it's there, stop the action ,if it isn't continue with the template.

// take search text from variable
var textContains = project.Variables["DealerName"].Value;
// get a list or search
var sourceList = project.Lists["Dealeri"];
// search in each line of list
lock(SyncObjects.ListSyncer)
{
    for(int i=0; i < sourceList.Count; i++)
    {
        // get line from list
        var str = sourceList[i];
        // check if line contains text, if there are matches return "yes"
        if (str.Contains(textContains))
            return "yes";
    }
}
// ifnothing found return "no"
return "no";

It can be obvious, but did you uncheck do not return a value option on C# module window?

project.Variables["isContain"].Value = project.Lists["Dealeri"].Any(x => x.IndexOf(project.Variables["DealerName"].Value) != -1).ToString();

or

if (project.Lists["Dealeri"].Any(x => x.IndexOf(project.Variables["DealerName"].Value) != -1))
    throw new Exception();
