不能隐式地将类型'int []'转换为'object []'？ [英] Cannot implicitly convert type 'int[]' to 'object[]'?

问题描述

大家好，



根据我的功能，我想将int []转换为object []。我试图这样做，但我不能转换它。



示例：

  int  [] intrs =  new   int  [] {< span class =code-digit> 400 ， 435 ， 446 ， 900 }; 
 
  object  [] obj = intrs; 

你能告诉我如何将int []转换为object []吗？



提前感谢..

解决方案

这里有一个非常好的解释，你应该阅读 - 无法将值类型数组转换为params对象[] [ ^ ]

  int  [] intrs =  new   int  [] { 400 ， 435 ， 446 ， 900 }; 
 
  object  [] obj =（ from  i  in  intrs 选择 i）.Cast< object>（）。ToArray（）; 

它会帮助你使用这种投射方法

你不能简单地转换一个数组 - 你不能明确地投了它。你需要做的是从现有数据创建一个新的对象[] 。

尽管如此：

  int  [] intrs =  new   int  [] { 400 ， 435 ， 446 ， 900 }; 
  object  [] obj = Array.ConvertAll（intrs，x = > （对象）x）的; 

Hi all,

Based on my functionality I want convert int[] to object[]. I tried to do this but I can't to convert this.

example:

int[] intrs = new int[] { 400, 435, 446, 900 };

            object[] obj = intrs;

Can you any one tell me how to convert int[] to object[]?

thanks in advance..

解决方案

There is a very nice explanation for the issue here that you should read - Can't convert value type array to params object[][^]

int[] intrs = new int[] { 400, 435, 446, 900 };

            object[] obj = (from i in intrs select i).Cast<object>().ToArray();

it will help you use this casting method

You can't convert an array that simply - you can't explicitly cast it either. What you have to do is create a new object[] from the existing data.
It's pretty easy though:

int[] intrs = new int[] { 400, 435, 446, 900 };
object[] obj = Array.ConvertAll(intrs, x => (object)x);
