How to Build a Chat Agent for Ollama Using C#

To begin, I create a new WinForms project in C# targeting .NET 10, and then install the OllamaSharp NuGet package.

In this example, txtOllamaUri, txtModel, and txtMessage are WinForms controls (for example, TextBox instances). Replace them with the corresponding controls or values from your own UI:

    Chat _chat;
    OllamaApiClient? _ollamaApiClient;
	
    uri = new Uri(txtOllamaUri.Text);
    _ollamaApiClient = new OllamaApiClient(uri);
    _ollamaApiClient.SelectedModel = txtModel.Text;

    _chat = new Chat(_ollamaApiClient);
	
    await foreach (var answerToken in _chat.SendAsync(txtMessage.Text))
        Console.Write(answerToken);
