让我们考虑以下 web.config 文件

通过阅读上述配置文件，我需要更改成员提供程序节点中类型字段的属性值。

    type="System.Web.Security.SqlMembershipProvider"

到新的价值

type="sample.SqlMembershipProvider"

通过 c#.net lambda 表达式

等待您的回复

我完成了解决方案

  var xDoc = XDocument.Load(inputPathToConfigFile);
                var ns = xDoc.Descendants().First(x => x.Name.LocalName == "configuration").Name.Namespace;

                var prop = xDoc.Descendants(ns + "membership")
                .First(p => p.Attribute("defaultProvider").Value == "SQLMembershipProvider");

               if(prop.HasAttributes)
               {
                   var prop1 = prop.Descendants(ns + "add").First(p => p.Attribute("type").Value == "System.Web.Security.SqlMembershipProvider");
                   prop1.Attribute("type").Value = "sample.membershipprovider";
                   xDoc.Save(inputPathToConfigFile);

               }

仅供参考...
