Based on Contain's Documentation the parameter for Contains could be string not a list of string. So it should be like this:

List TheListParameter = new List {"string1", "string2", "string3"};

var TheOutput = (from t in MyDC.SomeTable
                 where TheListParameter.Contains(t.SomeColumn.ToString())
                 select t.SomeColumn).ToList();

Or if you want to return a boolean result if MyDC.SomeTable.SomeColumn contains one of the TheListParameter's strings you can try something like this:

bool hasSameElements = MyDC.SomeTable.ToList()
                      .Select(c => c.SomeColumn)
                      .Intersect(TheListParameter).Any(); //True or False
