如何在winforms C＃中使用openfiledialog反序列化XML文件？ [英] How can I deserialize XML file with openfiledialog in winforms C#?

问题描述

我需要对我拥有的几个文件进行反序列化，问题是它只有一个，（我想这是因为在代码中，序列化器XML中有一部分，它指定了反序列化的文件路径，FileStream FS = new FileStream（"
file.xml，fileMode.Open，FileAccess.Read）;,表示路径"file.xml"，我需要替换为你的文件路径在openfiledialog窗口中选择，我已经尝试用"openfiledialog1。FileName"替换它，但是
它向我显示以下错误"System.InvalidOperationException：'XML文档中的错误（0,0）'内部异常XmlException：缺少根元素"。

I need to deserialize several files that I have, the problem is that it is only one, (I suppose it is because in the code, there is a part in the serializator XML, in which it specifies the file path to Deserialize, FileStream FS = new FileStream (" file.xml, fileMode.Open, FileAccess.Read) ;, indicates the path "file.xml", and I need to be replaced by the path of the file you choose in an openfiledialog window, I have already tried to replace it with "openfiledialog1. FileName "but it shows me the following error" System.InvalidOperationException: 'Error in the XML document (0,0)' Inner exception XmlException: The root element is missing ".

推荐答案

您好，

>> 我需要替换为您在openfiledialog窗口中选择的文件的路径，

您是如何用o替换文件路径的？ penFileDialog？

How did you replace the file path with openFileDialog?

请试试这个：

    if (openFileDialog1.ShowDialog() == DialogResult.OK)
    {
        FileStream FS = new FileStream(openFileDialog1.FileName, fileMode.Open, FileAccess.Read);
        //...
    }

问候，
