開發工具：VS 2015
開發環境：.Net 4.0
使用技術：WPF

本篇文章內容：
本地部署DeepSeek以后一般使用網頁工具（如Chatbox）或者DOS窗口與其對話。本篇文章使用WPF創建一個基礎版的對話工具。

一、搭建本地DeepSeek環境

我參考的是一下幾個教程：
1、DeepSeek本地搭建部署+搭建知識庫+智能體詳細圖文教程
2、【問題記錄】DeepSeek本地部署遇到問題
3、公司數據不泄露，DeepSeek R1本地化部署+web端訪問+個人知識庫搭建與使用，喂飯級實操教程，老舊筆記本竟跑出企業級AI
4、【大語言模型】本地快速部署Ollama運行大語言模型詳細流程

二、vs2015 創建WPF項目

三、相關代碼如下

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><!--第一個格子，AI對話格子--><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><!--第二個格子，用戶輸入框--><Grid Grid.Row="1" Grid.Column="0"><Grid.ColumnDefinitions><ColumnDefinition Width="8*" /><ColumnDefinition Width="2*"/></Grid.ColumnDefinitions><!--輸入信息框--><Grid Grid.Column="0"><TextBox Name="InputTextBox" HorizontalAlignment="Left" VerticalAlignment="Bottom" KeyDown="InputTextBox_KeyDown"Height="62" Width="522" Margin="61,0,0,14" /></Grid><!--發送信息按鈕框--><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>

后端代碼

}

四、內容介紹

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

其中這個代碼是本地DeepSeek默認的調用接口，如果自己修改了相關內容將此修改就可以

model = "deepseek-r1:1.5b"

這串代碼的意思是指定使用本地安裝的某個DeepSeek版本。

因為7b的版本在我電腦上太慢。所以直接使用最快的模型。

五、完成效果如下

這樣就搭建了基礎的對話模型。大家可以不斷優化，做一個自己的對話模型。
