Calling C# OpenLocationCode.Encode with length 2 fails 'Illegal code length 2'

[brewmanz]

Calling C# OpenLocationCode.Encode with length 2 fails with 'System.ArgumentException: Illegal code length 2.'.
I am using NuGet package OpenLocationCode by Jon McPherson, v2.1.0
This is for both GeoPoint and lat/long.
A length of 2 is valid (https://github.com/google/open-location-code/blob/master/docs/specification.md), giving a 'box' 20 degrees across.
My test code is

        [TestMethod]
        public void UT_HD0099_Encode_LL()
        {
            string res;
            res = Google.OpenLocationCode.OpenLocationCode.Encode(12.123456789, 123.123456789, 11);
            Assert.AreEqual("7Q4544FF+99P", res);
            res = Google.OpenLocationCode.OpenLocationCode.Encode(12.123, 123.123, 4);
            Assert.AreEqual("7Q450000+", res);
            res = Google.OpenLocationCode.OpenLocationCode.Encode(12.123, 123.123, 2);
            Assert.AreEqual("7Q000000+", res);
        }

(I don't like your 'insert code' formatting)

NB: I edited your comment to improve the code formatting.

We don't maintain the C# code in this repository, could you please open an issue here?

This bug is also affecting the Java implementation and has been since the initial implementation almost 5 years ago. And since I originally ported this from the Java implementation, this bug made its way here and has been here from the start.
We should probably also create an Issue/PR to the canonical repository to fix the Java implementation and add these test cases.
See open-location-code/java/~/OpenLocationCode.java#L191
