c# - 使用 C# 实现代码模板

Question

当我需要代码模板时，我可以使用Python如下。

templateString = """
%s 
%s
%s
"""

print templateString % ("a","b","c")

如何使用 C# 实现等效项？

我试过了

using System;

class DoFile {

    static void Main(string[] args) {
        string templateString = "
        {0}
        {1}
        {2}
        ";
        Console.WriteLine(templateString, "a", "b", "c");
    }
}

但是我得到了

dogen.cs(86,0): error CS1010: Newline in constant
dogen.cs(87,0): error CS1010: Newline in constant
dogen.cs(88,0): error CS1010: Newline in constant

当然 templateString = "{0}\n{1}\n{2}\n"; 有效，但我需要使用多行模板，因为 templateString 用于生成一个部分代码，而且真的很长。

Answer 1

您需要在第一个 引号之前放置一个@

templateString = @"
        {0}
        {1}
        {2}
        ";

让它成为 verbatim-string-literal

In a verbatim string literal, the characters between the delimiters are interpreted verbatim, the only exception being a quote-escape-sequence. In particular, simple escape sequences and hexadecimal and Unicode escape sequences *are not processed* in verbatim string literals. A verbatim string literal may span multiple lines.
