TwoSum Help

This is what I have so far:

C#
public class Solution {
    public int[] TwoSum(int[] nums, int target) {

        //declarations
        
        var usedPairs = new Dictionary <int, int>(){};
        int complement = 0;

        //traversal
        for(int i = 0; i<nums.Length; i++)
        {
            complement = target - nums[i];
            if(usedPairs.TryGetValue(complement, out int secondIndex))
            {
                return new int[]{i, secondIndex};
            }
            usedPairs[nums(i)] = i;
        }
        return new int[]{};
        
    }
}

C#
public class Solution {
    public int[] TwoSum(int[] nums, int target) {

        //declarations
        
        var usedPairs = new Dictionary <int, int>(){};
        int complement = 0;

        //traversal
        for(int i = 0; i<nums.Length; i++)
        {
            complement = target - nums[i];
            if(usedPairs.TryGetValue(complement, out int secondIndex))
            {
                return new int[]{i, secondIndex};
            }
            usedPairs[nums(i)] = i;
        }
        return new int[]{};
        
    }
}

I'm getting the following error:

Line 17: Char 23: error CS0149: Method name expected (in Solution.cs)

Line 17: Char 23: error CS0149: Method name expected (in Solution.cs)

with Line 17 being the line with

  usedPairs[nums(i)] = i;

  usedPairs[nums(i)] = i;

I'm not sure exactly what is wrong with this line

Well, nums is an array If you want to get an ith element from an array, use nums[i] Not nums(i)
