.net - 如何在 F# 中编写内联大字符串

Question

在 C# 中，我可以使用:

string myBigString = @"

<someXmlForInstance>
  <someChild />
</someXmlForInstance>

";

如何在 F# 中做到这一点？

Answer 1

在 F# 3.0、VS 2012 中，添加了对 triple-quoted strings 的支持.

In a triple-quoted string, everything between triple-quotes ("""...""") is kept verbatim; there is no escaping at all. As a result, if I want to have a bit of XAML as a string literal, it’s easy:

let xaml = """ 
<StackPanel xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
            xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
            Name="mainPanel"> 
  <Border BorderThickness="15.0" BorderBrush="Black"> 
    <StackPanel Name="stackPanel1"> 
      <TextBlock Text="Super BreakAway!" FontSize="24" HorizontalAlignment="Center" /> 
      <TextBlock Text="written in F#, by Brian McNamara - press 'p' to pause" 
                 FontSize="12" HorizontalAlignment="Center" /> 
      <Border BorderThickness="2.0" BorderBrush="Black"> 
        <Canvas Name="canvas" Background="White" /> 
      </Border> 
    </StackPanel> 
  </Border> 
</StackPanel>"""
