替换char [英] Replacing char

问题描述

你好，


我需要更换这个字符吗？与另一个char。

但是我无法解决这个问题。我尝试了这个，但是它没有工作：


str = str.Replace（chr（asc（194）），""）


有人可以提供帮助吗？

Hello,

I need to replace this char ? with another char.
However I am not able to acieve this. I tried this but it
doesnt work:

str = str.Replace(chr(asc(194)), "")

Can somebody help ?

推荐答案

替换需要两个字符或两个字符串。在你的情况下，试试：


Dim c As Char = Chr（194）

str = str.Replace（c.ToString，""）


或者为什么不只是str.replace（" ??"，""）？

The "replace" needs either two characters or two strings. In your case, try:

Dim c As Char = Chr(194)
str = str.Replace(c.ToString, "")

Or why not just str.replace("??", "")?

我尝试了两个版本，但它仍然无法正常工作。

是我正在阅读以下RSS

（ http://pluralsight.com/blogs/dbox/Rss.aspx ）并使用项目描述创建

文件。文件

仅包含带有奇怪字符的描述。这里

是我的完整代码：


Dim reader As New XmlTextReader

（" http://pluralsight.com/ blogs / dbox / Rss.aspx"）

Dim xmlDoc As New XmlDocument


xmlDoc.Load（读者）


Dim nodes As XmlNodeList = xmlDoc.SelectNodes

（" / rss / channel / item"）

dim i as integer = 0

>
For Each node As XmlNode In节点

尝试

strPost = node（" description"）。InnerXml

Dim c as char = Chr（194）

strPost = strPost.Replace（"？"，" XX"）

Dim fp As StreamWriter

dim strfile as string = Server.MapPath（" xml_news //"）

strfile = strfile& i.tostring（）

strfile = strfile& " .asp"

fp = File.CreateText（strfile）

fp.WriteLine（"< p>"& Server.HtmlDecode（strPost）

&"< / p>"）

fp.close（）

Catch ex As Exception

Response.Write（ex.Message（）&"< br>"）

结束尝试

i = i + 1

感谢您的帮助。

I tried both versions, but it still doesnt work. The thing
is that I am reading the following rss
(http://pluralsight.com/blogs/dbox/Rss.aspx) and creating
the file with the description of the item. The file
contains only the description with the strange chars. Here
is my complete code:

Dim reader As New XmlTextReader
("http://pluralsight.com/blogs/dbox/Rss.aspx")
Dim xmlDoc As New XmlDocument

xmlDoc.Load(reader)

Dim nodes As XmlNodeList = xmlDoc.SelectNodes
("/rss/channel/item")
dim i as integer = 0

For Each node As XmlNode In nodes
Try
strPost = node("description").InnerXml
Dim c as char = Chr(194)
strPost = strPost.Replace("?", "XX")
Dim fp As StreamWriter
dim strfile as string = Server.MapPath("xml_news//")
strfile = strfile & i.tostring()
strfile = strfile & ".asp"
fp = File.CreateText(strfile)
fp.WriteLine("<p>" & Server.HtmlDecode(strPost)
& "</p>")
fp.close()
Catch ex As Exception
Response.Write(ex.Message() & "<br>")
End Try
i = i + 1
Next

Thanks for any help.

Or why not just str.replace("?,", "")?
