Configuration.Save 方法

public:
 void Save();

public void Save ();

member this.Save : unit -> unit

Public Sub Save ()

例外

注解

方法 Save 保留自创建此 Configuration 对象以来已修改的任何配置设置。 如果配置文件不存在于 属性表示 FilePath 的物理位置，则会创建一个新的配置文件，以包含与继承的配置不同的任何设置。

如果配置文件自创建此 Configuration 对象以来已更改，则会发生运行时错误。

注解

方法Save基于 saveMode 参数在 对象中Configuration保留配置设置。

如果配置文件不存在于 属性表示 FilePath 的物理位置，则会创建一个新的配置文件，以包含与继承的配置不同的任何设置。

如果配置文件自创建此 Configuration 对象以来已更改，则会发生运行时错误。
