一些背景知识，我希望将 C# 应用程序中的现有代码从现有的 Microsoft.Azure.Management.Fluent （现已弃用）替换为较新的 Azure.ResourceManager 组件。
复制数据库的现有代码：
public async Task<bool> CopyDb(string? server, string? fromName, string? toName)
{
_log.LogInformation("Connecting to Azure");
var azure = GetAzureObject();
var servers = await azure.SqlServers.ListAsync();
var fromServer = servers.FirstOrDefault(f => server != null && server.Contains(f.Name));
if (fromServer == null)
{
throw new InvalidOperationException("Unable to find original database server");
}
var toNameBackup = $"{toName}-Old";
var existingDbs = await fromServer.Databases.ListAsync();
var fromDB = existingDbs.FirstOrDefault(f => f.Name.Equals(fromName));
if (fromDB == null)
{
throw new InvalidOperationException("Unable to find original database");
}
if (existingDbs.Any(a => a.Name.Equals(toNameBackup, StringComparison.OrdinalIgnoreCase))
&& existingDbs.Any(a => a.Name.Equals(toName, StringComparison.OrdinalIgnoreCase)))
{
_log.LogInformation("Deleting any existing backup called {0}", toNameBackup);
await fromServer.Databases.DeleteAsync(toNameBackup);
}
if (existingDbs.Any(a => a.Name.Equals(toName, StringComparison.OrdinalIgnoreCase)))
{
_log.LogInformation("Renaming target database from {0} to {1} (if exists)", toName, toNameBackup);
await (await fromServer.Databases.GetAsync(toName)).RenameAsync(toNameBackup);
}
_log.LogInformation("Copying database from from {0} to {1}", fromName, toName);
var result = await fromServer.Databases.
Define(toName).
WithSourceDatabase(fromDB).
WithMode(Microsoft.Azure.Management.Sql.Fluent.Models.CreateMode.Copy).CreateAsync();
return result != null;
}
private Microsoft.Azure.Management.Fluent.IAzure GetAzureObject()
{
var clientId = _configuration["AzureClientId"];
var clientSecret = _configuration["AzureClientSecret"];
var tenantId = _configuration["AzureTenantId"];
var subscriptionId = _configuration["AzureSubscriptionId"];
var credentials = Microsoft.Azure.Management.ResourceManager.Fluent.SdkContext.AzureCredentialsFactory.FromServicePrincipal(
clientId: clientId,
clientSecret: clientSecret,
tenantId: tenantId,
environment: Microsoft.Azure.Management.ResourceManager.Fluent.AzureEnvironment.AzureGlobalCloud);
return Microsoft.Azure.Management.Fluent.Azure.Configure().Authenticate(credentials).WithSubscription(subscriptionId);
}
较新的组件都与资源一起工作，我一直在努力如何使用较新的Azure.ArmClient进行一些操作。我已经能够用它查询找到我的 SQL 服务器和数据库。我什至可以删除一些数据库，但我无法弄清楚如何像上面的代码那样重命名或复制数据库。我知道有其他方法可以直接在 SQL 中执行此操作，但我更愿意了解如何在代码中执行此操作。
我浏览了 MS 文档，只能找到有关对象定义的信息，但没有示例。
我已经成功地进行了重命名：-
var backupDb = fromServer.GetSqlDatabase(toName);
if (backupDb != null && backupDb.Value != null)
{
// What do I pass in to the definition?
var moveDefinition = new SqlResourceMoveDefinition()
{
// What to set here?
};
await (await backupDb.Value.GetAsync()).Value.RenameAsync(moveDefinition);
}
我不确定如何定义 SqlResourceMoveDefinition。我也根本不知道如何像旧版 SDK 那样执行复制。
有人有关于如何在 C# 中实现这些操作的指南吗？
最终在https://learn.microsoft.com/en-us/dotnet/azure/sdk/resource-management?tabs=PowerShell工作后设法解决了这个问题。可能有更好的方法来做到这一点，当我找到它们时，如果其他人还没有找到答案，我会编辑答案！
public async Task<bool> CopyDb(string? server, string? fromName, string? toName)
{
_log.LogInformation("Connecting to Azure");
var azure = GetAzureSubscription();
var servers = azure.GetSqlServers().ToList();
var fromServer = servers.SingleOrDefault(f => server != null && f.Data != null && server.Contains(f.Data.Name));
if (fromServer == null)
{
throw new InvalidOperationException("Unable to find original database server");
}
var oldName = $"{toName}-Old";
var databases = fromServer.GetSqlDatabases();
_log.LogInformation("Check for any existing backup called {0}", oldName);
if (await databases.ExistsAsync(oldName))
{
_log.LogInformation("Deleting for any existing backup called {0}", oldName);
var oldBackup = await databases.GetAsync(oldName);
await oldBackup.Value.DeleteAsync(WaitUntil.Completed);
}
_log.LogInformation("Check target database {0} exists", toName, oldName);
if (await databases.ExistsAsync(toName))
{
_log.LogInformation("Renaming target database from {0} to {1}", toName, oldName);
var toDbBackup = await databases.GetAsync(toName);
var resourceIdString = toDbBackup.Value.Data.Id.Parent?.ToString();
var newResourceId = new ResourceIdentifier($"{resourceIdString}/databases/{oldName}");
var moveDefinition = new SqlResourceMoveDefinition(newResourceId);
var toDb = await toDbBackup.Value.GetAsync();
await toDb.Value.RenameAsync(moveDefinition);
}
_log.LogInformation("Copying database from from {0} to {1}", fromName, toName);
var fromDb = await databases.GetAsync(fromName);
var result = await databases.CreateOrUpdateAsync(WaitUntil.Completed, toName, fromDb.Value.Data);
_log.LogInformation("Operation completed!");
return result.HasValue;
}
private SubscriptionResource GetAzureSubscription()
{
var configValue = _configuration["AzureSubscriptionId"];
var subscriptionId = new ResourceIdentifier($"/subscriptions/{configValue}");
return GetAzureArmClient().GetSubscriptionResource(subscriptionId);
}
private ArmClient GetAzureArmClient()
{
var clientId = _configuration["AzureClientId"];
var clientSecret = _configuration["AzureClientSecret"];
var tenantId = _configuration["AzureTenantId"];
var credentials = new ClientSecretCredential(
clientId: clientId,
clientSecret: clientSecret,
tenantId: tenantId);
return new ArmClient(credentials);
}
虽然有点晚了，但我最近不得不研究一下我们正在实现的创建数据库副本的功能。我偶然发现了你的答案，它很有帮助，但它并没有完全创建数据库的精确副本。
只是想回复分享我在数据库副本中发现的内容（稍微扩展一下您的代码片段）：
_log.LogInformation("Copying database from from {0} to {1}", fromName, toName);
var fromDb = await databases.GetAsync(fromName);
SqlDatabaseData data = new SqlDatabaseData(new AzureLocation("East US"))
{
CreateMode = SqlDatabaseCreateMode.Copy,
SourceDatabaseId = fromDb.Value.Id
}
var result = await databases.CreateOrUpdateAsync(WaitUntil.Completed, toName, data);
_log.LogInformation("Operation completed!");
要获取更多示例，我可以找到 Azure 的 GitHub 存储库。供参考：https://github.com/Azure/azure-sdk-for-net/blob/main/sdk/sqlmanagement/Azure.ResourceManager.Sql/samples/Generate/Samples/Sample_SqlDatabaseCollection.cs.
