使用 WebBrowser 控件作为编辑器时出现问题
我目前正在开发一个项目，其中使用 WebBrowser 控件作为编辑器。我打开了设计模式，它似乎正在工作。我遇到的问题是，当我尝试保存文档并加载另一个文档时，它会弹出“此文档已被修改”。信息。我想做的就是这么简单，
if (frontPage)
{
frontPage = false;
frontContent = webEditor.DocumentText;
webEditor.DocumentText = backContent;
}
else
{
frontPage = true;
backContent = webEditor.DocumentText;
webEditor.DocumentText = frontContent;
}
就像我说的那样，每次我输入一些文本并运行此代码时，它都会弹出一条消息，说它已被修改，并询问我是否要保存。我该如何解决这个问题？
I am currently working on a project where I am using a WebBrowser control as an editor. I have design mode turned on and it seems to be working. The issue im having is when I try to save the Document and load another it pops up the "This document has been modified." message. What I am trying to do is as simple as this
if (frontPage)
{
frontPage = false;
frontContent = webEditor.DocumentText;
webEditor.DocumentText = backContent;
}
else
{
frontPage = true;
backContent = webEditor.DocumentText;
webEditor.DocumentText = frontContent;
}
Like I said everytime I enter some text and run this code it just pops up a message saying its been modified and asks if I want to save. How can I get around this?

您应该创建以下函数：
每次更改 DocumentText 之前都应该调用它。
You should create the following function:
It should be called every time before you change DocumentText.

DocumentText.更好的解决方案是在实际分配 html 代码之前写入空字符串：
WebBrowser1.Document.Write(string.Empty);
WebBrowser1.DocumentText = "您的代码";
better solution is to write empty string before you actually assign your html code:
WebBrowser1.Document.Write(string.Empty);
WebBrowser1.DocumentText = "your code";

Windows 窗体加载文档流（由 DocumentText 属性使用）的方式是导航到 about:blank，这将触发文档修改消息，然后在其 DocumentComplete 事件处理程序中加载该流。
由于您已经有一个文档，因此您可以跳过导航并直接通过其 IPersistStreamInit 接口将流加载到现有文档中，就像 Windows 窗体在其 DocumentComplete 事件处理程序中所做的那样。
The way Windows Forms load a document stream (used by the DocumentText property) is to navigate away to about:blank, which triggers the document modified message, then load the stream in its DocumentComplete event handler.
Since you already have a document, you can skip the navigation and load the stream into the existing document directly via its IPersistStreamInit interface like Windows Forms does in its DocumentComplete event handler.
试试这个
webEditor.ScriptErrorsSuppressed = true;确保您已在 IE 中禁用脚本调试（如果您已打开它）。
Try this
webEditor.ScriptErrorsSuppressed = true;Make sure you have disabled Script Debugging in IE in case you've turned it on.
