备注
The Providers element contains definitions for all event providers, hosted and nonhosted, used by the application.
The Providers element is optional. If your application does not use event classes (meaning the event or subscription rules query other data sources for events), you do not need event providers.
示例
The following example shows how to define both a hosted event provider and a nonhosted event provider.
<Providers>
<HostedProvider>
<ProviderName>StockEP</ProviderName>
<ClassName>StockData.StockProvider</ClassName>
<AssemblyName>
C:\EventProviders\CustomProviders\StockProvider.dll
</AssemblyName>
<SystemName>%SYSNAME%</SystemName>
<Schedule>
<StartTime>22:00:00</StartTime>
<Interval>P0DT00H05M00S</Interval>
