怎么把s里面的所有单引号换成双引号表示？
我希望输出的是
a said "b is a dog","so b is not a pig",c said.

Answer 1

string s = "a said 'b is a dog','so b is not a pig',c said.";//这里无法修改了
string c = s.Replace("\'", "\"");
Console.WriteLine(c); \\ Replace是非引用类型的修改，返回修改后的字符串，原字符串 不变

Answer 2

你可以使用字符串拼接啊：
s = "a said' "+" ' b is a dog' "+" ',' "+" 'so b is not a pig' "+" ',"+"c said."

Answer 3

s.replace("'","\"")

\" 转义符号，如果不对换成 /"

Answer 4

用转义字符替换。
