本次文章接上次写的“基础版”继续 WPF快速创建DeepSeek本地自己的客户端-基础思路版本

1 开发环境与工具

开发工具：VS 2015
开发环境：.Net 4.0
使用技术：WPF

本章内容：WPF实现一个进阶版的DeepSeek客户端。
效果图如下：

实现的功能：

1、实时接收DeepSeek回复的数据。
2、用户输入识别和AI回复识别使用不同的头像。
3、能够复制文字。

2 搭建本地DeepSeek环境

我参考的是一下几个教程：
1、DeepSeek本地搭建部署+搭建知识库+智能体详细图文教程
2、【问题记录】DeepSeek本地部署遇到问题
3、公司数据不泄露，DeepSeek R1本地化部署+web端访问+个人知识库搭建与使用，喂饭级实操教程，老旧笔记本竟跑出企业级AI
4、【大语言模型】本地快速部署Ollama运行大语言模型详细流程

3 vs2015 创建WPF项目

}

using System.Collections.Generic;
using System.Globalization;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Data;namespace WpfApplication2
{public class BooleanToVisibilityConverter : IValueConverter{public object Convert(object value, Type targetType, object parameter, CultureInfo culture){return value is bool && (bool)value ? Visibility.Visible : Visibility.Collapsed;}public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture){return value;}}
}

5 需要安装System.Net.Http库

Install-package System.Net.Http

通过以上步骤，我们成功创建了一个进阶版的DeepSeek本地客户端，具备了实时对话、消息区分和文本复制等功能。随着对WPF和DeepSeek的深入了解，您可以进一步扩展功能，比如增加更多的用户交互方式和优化UI设计。希望本文对您在WPF开发和DeepSeek应用方面有所帮助！
