C#实现本地Deepseek模型及其他模型的对话v1.4

前言

系 统：Window11
开发工具：Visual Studio 2022
相关技术：C# 、WPF .Net 8.0

1、C#实现本地AI聊天功能

WPF+OllamaSharpe实现本地聊天功能,可以选择使用Deepseek 及其他模型。

1. 新增根据聊天记录回复的功能。

2. 优化了部分ViewModel，将对应Model字段、属性移到Model中，方便后续扩展。

3. 新增读取外部数据回复问题功能，目前支持txt文件。

4. 新增添加图片提问题功能，模型需要支持视觉（如：minicpm-v:latest）。

5. 优化了类结构，创建对应的Model(MainWindowModel),将所有字段、属性移到Model。

6. 新增聊天记录窗体，修改了窗体加载时，加载聊天记录的功能。将其拆分成一个视图。

7. 移除了折叠栏功能，更新为Grid区域的显示与隐藏。 将聊天记录列表从主窗体中分离）。

8. 更新记录文件加载功能，显示提问日期。 新增选择文件类型设置预览图标。

9. 新增功能，新聊天后第一次提问完成后，保存的记录刷新到记录列表、记录删除功能。

10. 新增功能，创建新窗体判断显示Ollama服务运行状态。

2、相关依赖

OllamaSharpe：启用本地Ollama服务
Markdig.wpf : Markdown格式化输出功能。
Microsoft.Xaml.Behaviors.Wpf ：解决部分不能进行命令绑定的控件实现命令绑定功能。
Newtonsoft.Json：Json数据的序列化和反序列化。

3 界面预览

①界面预览

②界面预览-聊天记录

③界面预览-图像分析

④项目结构

Commands: 用于命令绑定
ExtensionTool:目前没啥大功能…
Services ：一些服务操作,如聊天数据处理、图像处理、序列化…
Models : 视图对应的模型，在类中创建一些字段、属性。
Views :视图以及一些视图控件的样式资源
ViewModels：视图模型，主要处理视图和模型的交互、以及一些业务处理
