Index was outside the bounds of the array

C#

So I have a class file. Inside the class is a void which is started in the Program.cs. I used 'LavaSurvival.Init("properties/lava.properties")' in the Program.cs. I'm only pretty new to coding, so it's probably something I didn't know XD. The problem is that I continue to get this error:

Type: IndexOutOfRangeException
Source: Test
Message: Index was outside the bounds of the array.
Target: Init
Trace: at Test.LavaSurvival.Init(String path) in C:\mypath=3\LavaSurvival.cs:line 61

UPDATE: Line 61 is the 'if (File.Exists(path))'

Heres the code for the void:

public static void Init(string path)
        {
           if (File.Exists(path))
            {
                string[] lines = File.ReadAllLines(path);
                foreach (string line in lines)
                {
                    if (line[0] != '!' && line != "" || line[0] != '#')
                    {
                        string key = line.Split('=')[0].Trim();
                        string value = line.Split('=')[1].Trim();
                        switch (key.ToLower())
