紫网站建设星巴克网络营销案例分析

开发工具：VS 2015
开发环境：.Net 4.0
使用技术：WPF

本篇文章内容：
本地部署DeepSeek以后一般使用网页工具（如Chatbox）或者DOS窗口与其对话。本篇文章使用WPF创建一个基础版的对话工具。

一、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

二、vs2015 创建WPF项目

三、相关代码如下

Windows窗口界面

<Window x:Class="DeepSeekAI2.MainWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:DeepSeekAI2"mc:Ignorable="d"Title="MainWindow" Height="680" Width="800"><Grid Margin="10,0,15,5"><Grid.RowDefinitions><RowDefinition Height="8.5*"/><RowDefinition Height="1.5*"/></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinition Width="750"/></Grid.ColumnDefinitions><!--第一个格子，AI对话格子--><Grid Grid.Row="0" Grid.Column="0"><ListBox Name="ChatListBox" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"><ListBox.ItemTemplate><DataTemplate><TextBlock Text="{Binding}" TextWrapping="Wrap" MaxWidth="730"/></DataTemplate></ListBox.ItemTemplate></ListBox></Grid><!--第二个格子，用户输入框--><Grid Grid.Row="1" Grid.Column="0"><Grid.ColumnDefinitions><ColumnDefinition Width="8*" /><ColumnDefinition Width="2*"/></Grid.ColumnDefinitions><!--输入信息框--><Grid Grid.Column="0"><TextBox Name="InputTextBox" HorizontalAlignment="Left" VerticalAlignment="Bottom" KeyDown="InputTextBox_KeyDown"Height="62" Width="522" Margin="61,0,0,14" /></Grid><!--发送信息按钮框--><Grid Grid.Column="1"><Button Name="SendButton" Content="Send" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="0,0,58,20" Width="90" Height="50" Click="SendButton_Click" FontFamily="Arial Black" FontSize="13" Foreground="#FF424234"/></Grid><Grid Grid.Column="1"><Button Name="SendButton1" Content="new" HorizontalAlignment="Right" VerticalAlignment="Bottom" Margin="0,0,2,60" Width="30" Height="30" Click="SendButton_Click1" FontFamily="Cambria" Foreground="#FF424234" Background="#FFB6F5C2"/></Grid></Grid></Grid>
</Window>

}

四、内容介绍

static string apiUrl = "http://localhost:11434/api/generate";

其中这个代码是本地DeepSeek默认的调用接口，如果自己修改了相关内容将此修改就可以

model = "deepseek-r1:1.5b"

这串代码的意思是指定使用本地安装的某个DeepSeek版本。

因为7b的版本在我电脑上太慢。所以直接使用最快的模型。

五、完成效果如下

这样就搭建了基础的对话模型。大家可以不断优化，做一个自己的对话模型。
