Question

c#里面如何分割字符串？将一个字符串按两个两个的分组成一个字符串组 比如说“abcdef"分成“ab""cd”"ef"

Answer 1

正则式，一句话，要引用using System.Text.RegularExpressions;
var str = "adkflsdllkqrr";
string[] result = Regex.Split(str, "(?<=\\G.{2})");

Answer 2

string a = "abcdefg";
string[] b = new string[a.Length];
for (int i = 0; i < a.Length / 2; i++)
{
b[i] = a.Substring(i*2,2);
Console.WriteLine(b[i]);
}

Answer 3

for循环 + substring()
