问题 I need to create one list based on two other lists. But seems like it does not remove the duplicates. Is this efficient way of merging two lists with no dupes? List<String[]> blocksComparisonSet1 = new List<String[]>(); List<String[]> blocksComparisonSet2 = new List<String[]>(); //we will combine list1 and list2 into this one List<String[]> blocksComparisonFinal = new List<String[]>(); //this is how I store data in each list //if both values found, add both of them (partial functions, FYI)
