使用 string.Join 用于连接数组或集合中的字符串。string[] words = { "Hello", "World" };string result = string.Join(" ", words);优点：简洁方便，适合处理数组或集合。缺点：需要传入分隔符，不适合普通字符串拼接。使用 string interpolation 适用于多行或复杂格式的字符串拼接。string name = "John";...
string.Join(string str,string[] strArr);//将数组strArr中的内容拼接成一个新的字符串,并在对应数组的每两项间添加分隔符str string strs=string.Join(",",string[]{"w","e","r","t"});//strs="w,e,r,t"; 3---》字符串常用的实例方法: 1、Contains 判断字符串中是否包含某个字符,返回boo...

Bool check = StringUtil.startWith(str, "abc"); printf("6. startWith (abc): %d\r\n", check); check = StringUtil.endWith(str, ",h"); printf("7. endWith (,h): %d\r\n", check); String joinstr = StringUtil.join(res, cnt); printf("8. join String: %s\r\n", joinstr);...
void main(){ char lj(char m[100],n[100]);//长度任意定，但必须分别大于你要连接的两个字符串 char a[100]，b[100];gets(a);gets(b);lj(a,b);puts(a);} char lj(char m[100],n[100]){ int i,j;for(i=0;m[i];i++);for(j=0;n[j]!='\0';i++,j++)m[i]...

String.Concat或String.Join 从集合联接字符串的另一个选项是使用String.Concat方法。 如果分隔符应分隔源字符串,请使用String.Join方法。 以下代码使用这两种方法合并单词数组: C# string[] words = {"The","quick","brown","fox","jumps","over","the","lazy","dog."};varunreadablePhrase =string.Concat...
Stringjoin(CharSequencedelimiter) 1. join方法接受一个参数,即用于分隔每个元素的分隔符,并返回一个包含所有元素的字符串。 示例代码 假设我们有一个包含字符串的List,我们想要将这些字符串连接成一个以逗号分隔的字符串: importjava.util.List;importjava.util.Arrays;publicclassJoinExample{publicstaticvoidmain(Stri...
