C# 注释


C# 注释

注释可以用来解释 C# 代码,并使其更易读。它还可以用来在测试备选代码时阻止执行。


单行注释

单行注释以两个正斜杠 (//) 开头。

// 和行尾之间的任何文本都被 C# 忽略(不会被执行)。

此示例在代码行之前使用单行注释

示例

// This is a comment
Console.WriteLine("Hello World!");

自己尝试 »

此示例在代码行的末尾使用单行注释

示例

Console.WriteLine("Hello World!");  // This is a comment

自己尝试 »


C# 多行注释

多行注释以 /* 开头,以 */ 结尾。

/**/ 之间的任何文本都将被 C# 忽略。

此示例使用多行注释(注释块)来解释代码

示例

/* The code below will print the words Hello World
to the screen, and it is amazing */
Console.WriteLine("Hello World!");

单行或多行注释?
