Invoice Total: '$1,234.56'
Line Items:
- Widget A (5 units): $500.00
- Service Fee: $234.56
- Tax: $100.00
正在使用“Azure.AI.DocumentIntelligence (.NET)”。 Extract tables from document
预期结果:
Table 1: 5 rows x 3 columns
Cell (0,0): Product | Quantity | Price
Cell (1,0): Widget A | 5 | $500.00

试试这些提示
Use Azure.AI.DocumentIntelligence to analyze an invoice from URL. Show me how to extract vendor name, invoice total, and line items with confidence scores in C#.
Show me how to use the prebuilt-layout model to extract all text content and tables from a PDF document using Azure Document Intelligence client in .NET.
Help me build a custom document model using Azure.AI.DocumentIntelligenceAdministrationClient. I have labeled training data in Azure Blob storage.
Show me how to authenticate to Azure Document Intelligence using DefaultAzureCredential in a .NET application. What endpoint format is required?
最佳实践
- Use DefaultAzureCredential in production for secure Microsoft Entra ID authentication instead of API keys
- Always check the Confidence property on extracted fields to verify data quality
- Reuse DocumentIntelligenceClient instances as they are thread-safe and designed for repeated use
避免
- Do not create a new client for each document analysis operation - this is inefficient
- Avoid using API keys in client-side applications - prefer Entra ID authentication
- Do not skip confidence score checking - low confidence values may indicate extraction errors
