使用 DataTools 实用程序提取 Azure SQL 数据库

Question

我想使用 VS2017 Data-Tools 编写一个实用程序，该实用程序将提取 Azure Sql 数据库并在本地文件存储上创建 dacpac。

我知道我可以使用 SQL Server 对象资源管理器并从中提取信息，但我想编写一个 c# 可执行文件来为我做同样的事情，这样我就可以自动化它并安排它每周发生一次。

我需要能够排除一些表，但除此之外它是一个直接的提取。这可能吗，有没有我可以用来开始的例子？抱歉，这对我来说是全新的，所以不知道从哪里开始。

using System;
using System.Collections.Generic;
using System.Configuration;
using System.Data.SqlClient;
using Microsoft.SqlServer.Dac;

private static string excludeSchemas = ConfigurationManager.AppSettings["ExcludeSchemas"];
private static string excludeTables = ConfigurationManager.AppSettings["ExcludeTables"];
private static string TableQuery = "SELECT SCHEMA_NAME(schema_id), name FROM sys.tables where SCHEMA_NAME(schema_id) not in ({0} ) and name  not in ({1}) order by schema_id,name";

static void Main(string[] args)
{
    Extract();
}

private static void Extract()
{
    var sourceConnectionString = ConfigurationManager.AppSettings["SourceDbConnection"];
    DacServices svc = new DacServices(sourceConnectionString);

    DacExtractOptions dacExtractOptions = new DacExtractOptions
    {
        ExtractApplicationScopedObjectsOnly = true,
        ExtractReferencedServerScopedElements = false,
        VerifyExtraction = false,
        Storage = DacSchemaModelStorageType.Memory
    };
    var tables = BuildTables();
    var dacPacDest = ConfigurationManager.AppSettings["DacPacDestination"];
    var sourceDb = ConfigurationManager.AppSettings["sourceDbName"];

    svc.Extract(dacPacDest,sourceDb, "Sample DACPAC", new Version(1, 0, 0), "Sample Extract", tables, dacExtractOptions);

}

private static IEnumerable<Tuple<string, string>> BuildTables()
{
    var tbls = new List<Tuple<string, string>>();
    var tblConnection = ConfigurationManager.AppSettings["SourceDbConnection"];
    using (SqlConnection connection = new SqlConnection(tblConnection))
    {
        connection.Open();
        string query = string.Format(TableQuery, excludeSchemas, excludeTables);
        using (SqlCommand command = new SqlCommand(query, connection))
        {
            using (SqlDataReader reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    tbls.Add(new Tuple<string, string>(reader.GetString(0), reader.GetString(1)));
                }
            }
        }
    }
    return tbls;
}
