在 String.Split 操作中指定空格的最佳方法 [英] Best way to specify whitespace in a String.Split operation

问题描述

我正在根据空格拆分字符串，如下所示:

I am splitting a string based on whitespace as follows:

string myStr = "The quick brown fox jumps over the lazy dog";

char[] whitespace = new char[] { ' ', '	' };
string[] ssizes = myStr.Split(whitespace);

在我想这样做的代码中到处定义 char[] 数组很烦人.有没有更高效的方法不需要创建字符数组(如果复制到不同的地方容易出错)?

It's irksome to define the char[] array everywhere in my code I want to do this. Is there more efficent way that doesn't require the creation of the character array (which is prone to error if copied in different places)?

推荐答案

如果你只是打电话:

string[] ssize = myStr.Split(null); //Or myStr.Split()

或:

string[] ssize = myStr.Split(new char[0]);

然后假设空格是分割字符.来自 string.Split(char[])方法的文档页面.

then white-space is assumed to be the splitting character. From the string.Split(char[]) method's documentation page.

如果分隔符参数为 null 或不包含任何字符，则假定空白字符为分隔符.空白字符由 Unicode 标准定义，如果它们被传递到 Char.IsWhiteSpace 方法.

If the separator parameter is null or contains no characters, white-space characters are assumed to be the delimiters. White-space characters are defined by the Unicode standard and return true if they are passed to the Char.IsWhiteSpace method.

总是，总是，总是阅读文档！

Always, always, always read the documentation!
