如何替换字符串中的花括号及其内容 [英] How to replace curly braces and its contents in a string

问题描述

我遇到了一个问题，试图用一个外部值替换用花括号划定的字符串的某些内容.

I have run into an issue of trying to replace certain contents of a string delineated with curly braces with an outside value.

相关代码示例:

string value = "6";
string sentence = "What is 3 x {contents}";
# insert some sort of method sentence.replace(value,"{contents}");

用值替换{contents}"的最佳方法是什么，因为花括号内的名称可能会改变，但无论名称如何，它都会包含在花括号内.

What is the best method for replacing "{contents}" with value, given that the name inside the curly braces may change but whatever the name, it will be contained within the curly braces.

我对正则表达式进行了一些研究，要么我迷失了概念，要么找不到相关的语法来完成我想要做的事情.这是实现这一目标的最佳方式吗?如果是，如何实现?如果不是，有什么更好的方法可以实现这一目标?

I looked a bit into regex and either the concepts were lost on me or I could not find relevant syntax to accomplish what I am trying to do. Is that the best way to accomplish this, and if so how? If not what would be a better method to accomplish this?

推荐答案

使用 Regex.Replace:

string value = "6";
string sentence = "What is 3 x {contents}";
var result = Regex.Replace(sentence, "{.*?}", value); // What is 3 X 6

MSDN 是个好地方开始理解正则表达式
