在C#中,可以使用以下方法根据多个空格来分割字符串:

使用 Split() 方法:

string input = "  Hello   World   How   are   you?  ";
string[] words = input.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);// words 数组包含: ["Hello", "World", "How", "are", "you?"]

使用正则表达式:

using System.Text.RegularExpressions;string input = "  Hello   World   How   are   you?  ";
string[] words = Regex.Split(input, @"\s+");// words 数组包含: ["", "Hello", "World", "How", "are", "you?", ""]

需要注意的是,使用正则表达式分割字符串时,结果数组可能会包含空字符串,因为正则表达式可能会匹配到连续的空白字符。如果需要移除这些空字符串,可以使用 Array.Where() 方法或 StringSplitOptions.RemoveEmptyEntries 选项。

使用 LINQ:

string input = "  Hello   World   How   are   you?  ";
string[] words = input.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries);
words = words.Where(w => !string.IsNullOrWhiteSpace(w)).ToArray();// words 数组包含: ["Hello", "World", "How", "are", "you?"]
