string Format转义大括号
String.Format("{0} world!","hello") //将输出 hello world!,没有问题,但是只要在第一个参数的任意位置加上一个大括号: String.Format("{0} wo{rld!","hello") //就会产生一个异常,异常信息是:Input string was not in a correct format. //解决办法:String.Format("{0} wo{{rld!","hello") //or String.Format("{0} wo{1}rld!","hello","{") //它们都将输出 hello wo{rld!
