比如字符串“baidu_{0}_{1}”怎么获取{}括号对的个数啊？这个字符串就是2个..因为我现在要根据这个参数个数预留文本框的个数..

Regex.Matches("baidu_{0}_{1}",@"\{[^}]+\}").Count
------解决方案--------------------------------------------------------
- C# code
string source = "baidu_{0}_{1}"; Regex reg = new Regex(@"(?is){\d*}"); MatchCollection mc = reg.Matches(source); MessageBox.Show(mc.Count.ToString());
------解决方案--------------------------------------------------------
- C# code
string str = "baidu_{0}_{1}"; Regex rgx = new Regex(@"{\d+}"); Console.WriteLine(rgx.Matches(str).Count);
------解决方案--------------------------------------------------------
Regex.Match(yourstr,"{[^{}]*?}").Count
