将 Azure 专用 SQL 池连接到 Azure 应用服务 (.NET Core)

Question

我们有一个 Azure 专用 SQL 池。我们希望利用 ADO.NET（SqlConnection 和 SqlCommand）从 Azure 应用服务（.NET Core 8 C#）连接到它。

实现此功能需要采取哪些步骤？我们是否需要将应用服务的托管标识添加到 SQL 池中？

Answer 1

我尝试通过我的

Dedicated pool

、

Asp.net

Web 应用程序访问 Azure Synapse

.Net 6.0

，它运行成功：-

In Services Folder >

ProductService.cs:-

using sqlapp.Models;
using System.Data.SqlClient;

namespace sqlapp.Services
{

    public class ProductService : IProductService
    {
        private readonly IConfiguration _configuration;
        public ProductService(IConfiguration configuration)
        {
            _configuration = configuration;
        }
        private SqlConnection GetConnection()
        {

            return new SqlConnection(_configuration.GetConnectionString("SQLConnection"));
        }
        public List<Product> GetProducts()
        {
            List<Product> _product_lst = new List<Product>();
            string _statement = "SELECT ProductID,ProductName,Quantity from Products";
            SqlConnection _connection = GetConnection();

            _connection.Open();

            SqlCommand _sqlcommand = new SqlCommand(_statement, _connection);

            using (SqlDataReader _reader = _sqlcommand.ExecuteReader())
            {
                while (_reader.Read())
                {
                    Product _product = new Product()
                    {
                        ProductID = _reader.GetInt32(0),
                        ProductName = _reader.GetString(1),
                        Quantity = _reader.GetInt32(2)
                    };

                    _product_lst.Add(_product);
                }
            }
            _connection.Close();
            return _product_lst;
        }

    }
}

In Pages Folder > Index.cshtml:-

@page
@model IndexModel
@{
    ViewData["Title"] = "Home page";
}

<div class="text-center">
    <h1 class="display-4">This is a list of Products</h1>    
    <table class="table table-bordered">
  <thead>
    <tr>
      <th scope="col">Product ID</th>
      <th scope="col">Product Name</th>
      <th scope="col">Quantity</th>      
    </tr>
  </thead>
   <tbody>
    
        @foreach(var product in Model.Products)
                {
                    <tr>
                    <th scope="row">@product.ProductID</th>
                    <td>@product.ProductName</td>
                    <td>@product.Quantity</td>
                    </tr>
                }                
    
    </tbody>
  </table>
</div>

Azure synapse 专用池 ado.net 连接字符串，参考：-

Name: SQLConnection
Value: Server=tcp:xxxorkspace45.sql.azuresynapse.net,1433;Initial Catalog=pooldb;Persist Security Info=False;User ID=xxxxxser;Password=Wxxxxxx;MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;

在Web应用程序的连接字符串中添加以下设置：-

Azure Synapse 网络设置，允许从所有 Azure 服务进行访问：-

输出：-
