我有以下代码似乎引发了“无效的跨线程访问”。我似乎无法弄清楚为什么。我正在从 URL 加载远程 xml 文件,但是,在解析该 XML 时,我总是收到此错误。有什么建议么?
using (StreamReader streamReader = new StreamReader(response.GetResponseStream()))
{
string xml = streamReader.ReadToEnd();
using (XmlReader reader = XmlReader.Create(new StringReader(xml)))
{
reader.ReadToFollowing("channel");
reader.MoveToFirstAttribute();
reader.ReadToFollowing("title");
output.AppendLine("Title: " + reader.ReadElementContentAsString());
reader.ReadToFollowing("description");
output.AppendLine("Desc: " + reader.ReadElementContentAsString());
textBox1.Text = output.ToString(); //Invalid cross-thread access.
}
}
我尝试解析的 XML 如下所示,我只是在尝试解析点点滴滴,因为我继续学习如何使用 c# 解析不同类型的 XML:
<?xml version="1.0" encoding="utf-8"?>
