大多数effecient方式来连接字符串 [英] Most effecient way to concatenate strings

问题描述

什么是连接字符串的最有效方法是什么？

What's the most efficient way to concatenate strings?

推荐答案

的 StringBuilder.Append（）方法比使用+运算符好得多。但我发现，当串联小于1000，的string.join（）甚至比更有效的StringBuilder 。

The StringBuilder.Append() method is much better than using the + operator. But I've found that, when the concatenations are less than 1000, String.Join() is even more efficient than StringBuilder.

StringBuilder sb = new StringBuilder();
sb.Append(someString);

与的string.join 唯一的问题是，你必须有一个共同的分隔符来连接字符串。

The only problem with String.Join is that you have to concatenate the strings with a common delimiter.

string key = String.Join("_", new String[] 
{ "Customers_Contacts", customerID, database, SessionID });
