Reset to default
Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.
It falls back to sorting by highest score if no posts are trending.
All string literals in VB.NET are verbatim string literals. Simply write
Dim str As String = "c:\folder1\file1.txt"
VB.NET doesn’t support inline control characters. So backslashes are always interpreted literally.
The only character that needs to be escaped is the double quotation mark, which is escaped by doubling it, as you do in C#
Dim s As String = """Ahoy!"" cried the captain." ' "Ahoy!" cried the captain.
@MarkJ already pointed this out in @Jon Skeet’s post.
VB.Net supports this
abomination feature, if you absolutely need to use a verbatim via an inline XML Literal.
Consider Caching the String! Don’t evaluate this every time…
Imports System.Xml.Linq Dim cmdText as String = <![CDATA[ SELECT Field1, Field2, Field3 FROM table WHERE Field1 = 1 ]]>.Value
VB14 / VS2015 supports multi-line strings without any shenanigans.
Dim cmdText as String = " SELECT Field1, Field2, Field3 FROM table WHERE Field1 = 1"
VB doesn’t treat
\ as an escape character anyway, so you can just write the string as a normal literal:
Dim str = "c:\folder1\file1.txt"
As far as I’m aware, VB doesn’t have any way of achieving the other major goal of verbatim string literals, that of allowing multiple lines – you have to use
VbCrLf for that, I believe. (Or
Environment.NewLine of course – it depends on your requirements. Sometimes you want the system-specific line separator; sometimes you want a specific one as required by a particular protocol etc.)
When in doubt look at this comparison page:
'No string literal operator Dim filename As String = "c:\temp\x.dat"
// String literal string filename = @"c:\temp\x.dat"; string filename = "c:\\temp\\x.dat";
VB.NET do not recognize “\” as an escape character.
But, maybe you may use further solution (take into account, that it’s works slowly than concatenation, e.g.):
Dim s As String = Regex.Unescape("c:\\folder1\\file1.txt\nc:\\folder1\\file2.txt\nc:\\folder1\\file3.txt")
In this case, string “s” contains three lines.
Symbol “\” is protect next “\” from regex method Unescape(), that’s why it repeat twice each time.
“\n” is a C#-like “new line” special character. You also may use “\t” (tab), and so on.
Dim sourceText As String = <string> Imports Microsoft.VisualBasic Imports System Imports System.Collections Imports Microsoft.Win32 Imports System.Linq Imports System.Text Imports Roslyn.Compilers Imports System.ComponentModel Imports System.Runtime.CompilerServices Imports Roslyn.Compilers.VisualBasic Namespace HelloWorld Module Program Sub Main(args As String()) Console.WriteLine("Hello, World!") End Sub End Module End Namespace </string>
VB XML literals unfortunately will not work in a .vbhtml razor page. Hopefully that will change in the next release.
