语法
声明
<GuidAttribute("4FFCB8E5-7B15-4b81-AC4E-99A2181AD33E")> _
<SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel := True)> _
<SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel := True)> _
Public Class SPContentDatabaseCollection _
Inherits SPBaseCollection
用法
Dim instance As SPContentDatabaseCollection
[GuidAttribute("4FFCB8E5-7B15-4b81-AC4E-99A2181AD33E")]
[SharePointPermissionAttribute(SecurityAction.InheritanceDemand, ObjectModel = true)]
[SharePointPermissionAttribute(SecurityAction.LinkDemand, ObjectModel = true)]
public class SPContentDatabaseCollection : SPBaseCollection
备注
使用SPSite类的或的SPWorkItemCollection类的**ContentDatabase()**属性返回的工作项集合的网站集的内容数据库。使用SPWebApplication类的ContentDatabases属性返回所使用的 Web 应用程序的内容数据库的集合。
若要添加内容数据库，请使用**Add()**方法。
使用索引器从集合中返回一个内容数据库。例如，如果该集合分配给名为myContentDatabases的变量中，使用在 C# myContentDatabases[index]或myContentDatabases(index)在 Visual Basic.NET 中，其中index是数据库集合中的索引号，或是该内容数据库的 GUID。
示例
下面的代码示例显示在Microsoft SharePoint Foundation服务器场中的所有 SharePoint Web 应用程序的内容数据库的信息。
Dim services As SPServiceCollection = SPFarm.Local.Services
Dim service As SPService
For Each service In services
If TypeOf service Is SPWebService Then
Dim webService As SPWebService = CType(service, SPWebService)
Dim webApplications As SPWebApplicationCollection = webService.WebApplications
Dim webApplication As SPWebApplication
For Each webApplication In webApplications
Dim contentDBs As SPContentDatabaseCollection = webApplication.ContentDatabases
Dim contentDB As SPContentDatabase
For Each contentDB In contentDBs
Response.Write((webApplication.DisplayName + " :: "
+ contentDB.CurrentSiteCount.ToString() + " :: "
+ contentDB.MaximumSiteCount.ToString() + " :: "
+ contentDB.Name + "<BR>"))
Next contentDB
Next webApplication
End If
Next service
SPServiceCollection services = SPFarm.Local.Services;
foreach (SPService service in services)
{
if (service is SPWebService)
{
SPWebService webService = (SPWebService)service;
SPWebApplicationCollection webApplications = webService.WebApplications;
foreach (SPWebApplication webApplication in webApplications)
{
SPContentDatabaseCollection contentDBs = webApplication.ContentDatabases;
foreach (SPContentDatabase contentDB in contentDBs)
{
Response.Write(webApplication.DisplayName + " :: "
+ contentDB.CurrentSiteCount.ToString() + " :: "
+ contentDB.MaximumSiteCount.ToString() + " :: "
+ contentDB.Name + "<BR>");
}
}
}
}
