How to define CustomAnalyzer through C# code when creating Azure Search Index

I saw the note from here: https://learn.microsoft.com/en-us/rest/api/searchservice/custom-analyzers-in-azure-search that: Custom analyzers that you create are not exposed in the Azure portal. The only way to add a custom analyzer is through code that makes calls to the API when defining an index.

Currently I am using the following C# code to create the Azure search index:

var definition = new Microsoft.Azure.Search.Models.Index()
{
    Name = "test-index",
    Fields = new List<Field>
    {
        new Field("field1", Microsoft.Azure.Search.Models.DataType.String) { IsKey = false, IsSearchable = false, IsFilterable = false, IsSortable = false, IsFacetable = false, IsRetrievable = true }
    }
}
searchClient.Indexes.CreateOrUpdate(myIndex);

Is there a way that I can add some code in here such as:

var analyzer = new CustomAnalyzer();
analyzer.Tokenizer = TokenizerName.Keyword;
analyzer.TokenFilters.Add(TokenFilterName.Lowercase);

and then add this custom analyzer in my code above somewhere to let "field1" use my defined analyzer?

Yes, you can add custom analyzers through the SDK, here are some examples: https://github.com/Azure/azure-sdk-for-net/blob/master/sdk/search/Microsoft.Azure.Search/tests/Tests/CustomAnalyzerTests.cs
