Question

只是好奇它。我想知道为什么：

string str = @"//
    // Use a new char[] array of two characters (\r and \n) to break
    // lines from into separate strings. \n Use RemoveEmptyEntries
    // to make sure no empty strings get put in the string array. 
    //";

对richTextBox的结果文本是：

//
    // Use a new char[] array of two characters (\r and \n) to break
    // lines from into separate strings. \n Use RemoveEmptyEntries
    // to make sure no empty strings get put in the string array. 
    //

但

string str = @"//
    // Use a new char[] array of two characters (\r and \n) to break
    // lines from into separate strings."+" \n" + @" Use RemoveEmptyEntries
    // to make sure no empty strings get put in the string array. 
    //";

对richTextBox的结果文本是：

//
    // Use a new char[] array of two characters (\r and \n) to break
    // lines from into separate strings. 
 Use RemoveEmptyEntries
    // to make sure no empty strings get put in the string array. 
    //

Answer 1

在您的中心字符串之前没有文字@＆＃34; \ n＆＃34; 等价物是

string str = @"//
// Use a new char[] array of two characters (\r and \n) to break
// lines from into separate strings."+ @" \n" + @" Use RemoveEmptyEntries
// to make sure no empty strings get put in the string array. 
//";

\是普通字符串中的转义字符，但字符串文字完全按原样使用内容，除非是＆＃34;被转义为＆＃34;＆＃34;

Answer 2

因为＆＃34; \ n＆＃34;之前没有@在你的第二个例子。 @（逐字字符串文字）之后的任何转义序列都将被忽略。在你的第一个例子中，它被忽略但不在第二个例子中。
