工作总结 string类型保存 "" 这种类型

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
//DateTime st = new DateTime(2018, 5, 6, 20, 24, 24);
//Console.WriteLine(st);
//Console.WriteLine(st.ToString("yyyy:MM:dd,hh:mm:ss"));
//Console.WriteLine(st.ToString("yyyy:MM:dd,HH:mm:ss"));

string sds1 = @"IFERROR(IF(Z{0}-J{0}=0,"",(Z{0}-J{0})+(Z{0}<J{0})),"")";
//之前这样写 不对的  "" 它只会输出一个“
Console.WriteLine(sds1);
//输出两个 要写  """"
string sds = @"IFERROR(IF(Z{0}-J{0}=0,"""",(Z{0}-J{0})+(Z{0}<J{0})),"""")";
Console.WriteLine(sds);
sds = string.Format(sds, (3 + 1));
Console.WriteLine(sds);
//@ 中 ""         @"""   会报错         @""""        \"  只输出一个 "
string ssss = @"""";
Console.WriteLine(ssss);
//sds = string.Format(forat, (data4 + 1));
