如何在字符串变量中插入“字符？

Question

如何插入？

Dim SpCharacter As String = " " "

或

Dim XMLSitemap As String = "<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">"

插入所有内容“和＆gt; 等

Answer 1

你需要通过加倍来逃避它：

Dim SpCharacter As String = " "" "

Dim XMLSitemap As String = "<urlset xmlns=""http://www.sitemaps.org/schemas/sitemap/0.9"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xsi:schemaLocation=""http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"">"

请参阅MSDN上的String Basics in Visual Basic：

  

Visual Basic将字符串文字中的两个引号解释为字符串中的一个引号。

Answer 2

在VB.NET中，您可以通过连续两次传递来转义"：

Dim SpCharacter As String = " "" "

或

Dim XMLSitemap As String = "<urlset xmlns=""http://www.sitemaps.org/schemas/sitemap/0.9"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xsi:schemaLocation=""http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"">"
