如何修复加载配置文件时"配置系统初始化失败/ Root元素丢失"错误？

use*_*526 10 c# config

我在c#windows应用程序中遇到此错误:"配置系统无法初始化".

它工作正常.突然间我得到了这个例外.它显示内部异常细节为"缺少根元素".(C:\ Users\company\AppData\Local\Clickbase_Corp_Sverige_AB\TouchStation.vshost.exe_Url_no1nets4fg3oy2p2q2pnwgulbvczlv33\1.1.0.12\user.config)"}.当我尝试从Settings.cs类中获取值时会发生这种情况.

在program.cs文件中,编写了以下代码

if (Properties.Settings.Default.CallUpgrade)
            {
                Properties.Settings.Default.Upgrade();
                Properties.Settings.Default.CallUpgrade = false;
                Properties.Settings.Default.Save();                
            }

并调用settings.cs类,其中下面的代码抛出异常

    [global::System.Configuration.UserScopedSettingAttribute()]
    [global::System.Diagnostics.DebuggerNonUserCodeAttribute()]
    [global::System.Configuration.DefaultSettingValueAttribute("True")]

    public bool CallUpgrade {
        get {
            return ((bool)(this["CallUpgrade"]));
        }
        set {
            this["CallUpgrade"] = value;
        }
    }

除了Akram Shahda的回答:我遇到了同样的问题(配置系统初始化失败/ root元素丢失).AppData文件夹中的.config文件为空.通过删除AppData文件夹中的.config文件解决了该问题.

Add*_*dds 6

以防万一有人读到这个：

对我来说，我只需转到 user.config 位置即可解决问题，对于这个问题，它是：

(C:\Users\company\AppData\Local\Clickbase_Corp_Sverige_AB\TouchStation.vshost.exe_Url_no1nets4fg3oy2p2q2pnwgulbvczlv33\1.1.0.12\user.config)"

我删除了配置文件并重新启动了 Visual Studio，它起作用了。

希望这可以帮助！

谢谢

XmlException缺少标题Root元素的原因意味着您尝试加载的XML文档（此处的配置文件）的格式不正确，更确切地说，它缺少根节点。

每个XML文件必须具有一个根元素/节点，该根元素/节点将所有其他元素都包含在内。

您的文件必须如下所示：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="userSettings" 
            type="System.Configuration.UserSettingsGroup, System,
            Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
        </sectionGroup>
    </configSections>
    <userSettings>
        <WindowsFormsApplication.Properties.Settings>
        </WindowsFormsApplication.Properties.Settings>
    </userSettings>
</configuration>

  • 可能是问题所在，但是`&lt;？xml ...？&gt;`不被称为根节点。这是一条处理指令。“ &lt;configuration&gt;”是根。 (3认同)
