【问题描述】：
我正在尝试使用 Kusto C# SDK 运行 purge 命令以进行测试
我正在执行.show purges，据我所知，如果我可以执行此命令，那么我也可以执行其他清除命令
我已经使用了带有摄取前缀的连接字符串（如这个答案https://github.com/Azure/azure-kusto-python/issues/165），但我无法使用清除命令
public AdxConnection()
{
// https://ingest-mycluster.myregion.kusto.windows.net
var connStringBuilder = new KustoConnectionStringBuilder(_connectionString)
.WithAadApplicationKeyAuthentication(_clientId, _clientSecret, _tenantId);
_adminProvider = KustoClientFactory.CreateCslAdminProvider(connStringBuilder);
}
public async Task Purge()
{
var purgeCommand = CslCommandGenerator.GenerateShowPurgeCommand(_database);
await _adminProvider.ExecuteControlCommandAsync(_database, purgeCommand);
}
这是 Kusto 的回复

}
}. Query: '.show database environment1 purge operations'
*编辑：
将GenerateShowPurgeCommand 替换为GenerateDmPurgesShowCommand 即可解决问题。但是，在运行GenerateDmPurgeTableRecordsFirstPhase 时，我遇到了另一个错误

},

}
}
我是否需要联系 Kusto 团队将 EnabledForPurge 设置为 true，或者我可以自己使用命令来执行此操作？这不是我在文档中找到的内容。
