通过连接字符串在 virtuoso 服务器中设置连接超时
我使用以下配置在 Windows 上启动了 virtuoso 服务（这是配置文件的重要部分）：
ResultSetMaxRows = 10000
MaxQueryCostEstimationTime = 40000 ; in seconds
MaxQueryExecutionTime = 60000 ; in seconds
DefaultQuery = select * where{?x ?y ?z}
DeferInferenceRulesInit = 0 ; controls inference rules loading
我正在使用 dotNetRDF 库对本地服务器进行本地查询（该库使超时为 30 秒），但我可以通过在启动对象时发送连接字符串来覆盖默认超时：
VirtuosoManager manager = new VirtuosoManager("Server=localhost;Uid=dba;pwd=dba;Connection Timeout=500");
它仍然在 30 秒超时（如果我的查询足够复杂，需要在 30 秒以上处理......
我的项目使用一些复杂的查询，所以我需要超时属性尽可能大，我如何覆盖该属性？
I started the virtuoso service on windows with the following configurations (this is the important part of the config file):
ResultSetMaxRows = 10000
MaxQueryCostEstimationTime = 40000 ; in seconds
MaxQueryExecutionTime = 60000 ; in seconds
DefaultQuery = select * where{?x ?y ?z}
DeferInferenceRulesInit = 0 ; controls inference rules loading
I'm using the dotNetRDF library to make local queries to the local server (The library makes the timeout 30seconds) , but I can override the default timeout by sending a connection string when starting the object:
VirtuosoManager manager = new VirtuosoManager("Server=localhost;Uid=dba;pwd=dba;Connection Timeout=500");
it still times out at 30seconds (if my query is complex enough to process in more than 30 seconds...
My project uses some complex queries, so I need the timeout property as large as possible , how can I override that property ?

Virtuoso ADO.Net Provider DBcommand 类具有 CommandTimeout 属性，默认值为 30 秒，详见 VirtuosoCommand 类文档。
这是您遇到的超时（不是连接超时）。
从修订版 2148 开始，dotNetRDF 库允许根据需要设置此属性值。
The Virtuoso ADO.Net Provider DBcommand class has a CommandTimeout property, with a default value of 30 seconds, as detailed in the VirtuosoCommand class documentation.
This is the timeout you are hitting (not a Connection Timeout).
As of revision 2148, the dotNetRDF library allows this property value to be set as required.
