备注
Web.config 修改的集合是一组命令的当处理 web.config 操控程序在Microsoft SharePoint Foundation中，请更改 web.config 文件的状态。您可以一起使用这些命令，以确保它们适用所需的标签和属性在 web.config 中的一组。每次修改表示为管理对象模型中的对象。
使用SPWebApplication或SPWebService类的WebConfigModifications属性可在 Web 应用程序或 Web 服务中的所有 Web 应用程序中获取的 web.config 修改集合。若要应用您定义通过SPWebConfigModification类到服务器场中的 web.config 文件的修改， ApplyWebConfigModifications上调用方法的当前内容 Web 服务对象，按如下所述： SPWebService.ContentService.ApplyWebConfigModifications
示例
下面的示例将安全控制项添加到 web.config 整个服务器场中的安全控件一节。
Dim myService As SPWebService = SPWebService.ContentService
Dim myModification As New SPWebConfigModification()
myModification.Path = "configuration/SharePoint/SafeControls"
myModification.Name = "SafeControl[@Assembly='MyCustomAssembly'][@Namespace='MyCustomNamespace'][@TypeName='*'][@Safe='True']"
myModification.Sequence = 0
myModification.Owner = WebConfigModificationFeatureReceiver.OwnerId
myModification.Type = SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode
myModification.Value = "<SafeControl Assembly='MyCustomAssembly' Namespace='MyCustomNamespace' TypeName='*' Safe='True' />"
myService.WebConfigModifications.Add(myModification)
myService.Update()
myService.ApplyWebConfigModifications()
SPWebService myService = SPWebService.ContentService;
SPWebConfigModification myModification = new SPWebConfigModification();
myModification.Path = "configuration/SharePoint/SafeControls";
myModification.Name = "SafeControl[@Assembly='MyCustomAssembly'][@Namespace='MyCustomNamespace'][@TypeName='*'][@Safe='True']";
myModification.Sequence = 0;
myModification.Owner = WebConfigModificationFeatureReceiver.OwnerId;
myModification.Type = SPWebConfigModification.SPWebConfigModificationType.EnsureChildNode;
myModification.Value = "<SafeControl Assembly='MyCustomAssembly' Namespace='MyCustomNamespace' TypeName='*' Safe='True' />";
myService.WebConfigModifications.Add(myModification);
myService.Update();
myService.ApplyWebConfigModifications();
