此範例展示如何使用 Microsoft Agent Framework for .NET 建立智慧旅遊規劃代理。該代理可自動為全球隨機目的地生成個人化的一日遊行程。
AzureCliCredential (az login) 進行安全登入GetRandomDestination() 函數給代理使用graph LR
A[用戶請求] --> B[人工智能代理]
B --> C[Azure OpenAI（響應 API）]
B --> D[取得隨機目的地工具]
C --> E[旅行行程]
D --> E
az login 登入# zsh/bash
export AZURE_OPENAI_ENDPOINT=https://<your-resource>.openai.azure.com
export AZURE_OPENAI_DEPLOYMENT=gpt-5-mini
# 然後登入，以便 AzureCliCredential 可以取得令牌
az login
# PowerShell
$env:AZURE_OPENAI_ENDPOINT = "https://<your-resource>.openai.azure.com"
$env:AZURE_OPENAI_DEPLOYMENT = "gpt-5-mini"
# 然後登入，以便 AzureCliCredential 可以取得憑證令牌
az login
執行此範例程式碼，
# zsh/bash
chmod +x ./01-dotnet-agent-framework.cs
./01-dotnet-agent-framework.cs
或使用 dotnet CLI：
dotnet run ./01-dotnet-agent-framework.cs
