C#IEnumerable< Object>串 [英] C# IEnumerable<Object> to string

问题描述

出于记录目的，我想在object []数组上调用每个对象的.ToString()方法.如何以最简单的方式做到这一点?

For logging purposes, I would like to call the .ToString() method of every object on an object[] array. How can I do this in the simplest way?

说我有:

   myArray = new Object[]{"astring",1, Customer}

   Log(????);

如何传递一个字符串，例如它的值等于:

How can I pass a string such as its value is equal to:

"astring".ToString()+1.ToString()+Customer.ToString()

或者更好，每个值之间用逗号分隔.

Or better, with comma between each value.

推荐答案

像这样:

Log(String.Join(", ", myArray.Select(o => o.ToString()).ToArray()));

Update:

从框架4开始，Join方法也可以采用IEnumerable<string>，因此您不需要ToArray:

From framework 4 the Join method can also take an IEnumerable<string>, so you don't need the ToArray:

Log(String.Join(", ", myArray.Select(o => o.ToString())));
