如何检查多维数组行是否包含非零值 [英] How to check if multidimensional array row contains non-Zero value

问题描述

关于 C# 中多维数组的一个简短问题.

如何检查多维数组的一行是否包含非零值?在 Matlab 中，any"命令完全符合我的需要.

最后，我需要将请求置于 while 条件中.Matlab 中的意思:while(any(array[1,2,:])) --> 意思是:while(any-entry-of-the-row-is-not-Zero)...

我已经尝试过 Array.Exists() 或 Array.Find() 但它似乎只适用于一维数组.

谢谢

解决方案

您有几个选择

myMultiArray.Any(row => row.Contains(Something));

或按照 Sriram Sakthivel 的建议

foreach(myMultiArray 中的 var 行)if(row.Contains(Something)//找到了！foreach(myMultiArray 中的 var 行)if(row.IndexOf(Something) >= 0)//找到了！

更具体地说是您的问题

myMultiArray.Any(row => row.Any(cell => cell != 0));foreach(myMultiArray 中的 var 行)foreach(myMultiArray 中的 var 单元格)如果(单元格！= 0)//找到了！for(int i = 0; i

Just a short question regarding multidimensional arrays in C#.

How can I check if one row of a multidimensional array contains a non-Zero value? In Matlab, the "any"-command does exactly what I need.

Finally I need to put the request into a while condition. Means in Matlab: while(any(array[1,2,:])) --> which means: while(any-entry-of-the-row-is-not-Zero)...

I tried already the Array.Exists() or Array.Find() but it seems to work only with one-dimensional arrays.

Thanks

解决方案

You have a couple options

myMultiArray.Any(row => row.Contains(Something));

or as Sriram Sakthivel Suggested

foreach(var row in myMultiArray)
    if(row.Contains(Something)
        //Found it!

foreach(var row in myMultiArray)
    if(row.IndexOf(Something) >= 0)
        //Found it!

More spefically to your question

myMultiArray.Any(row => row.Any(cell => cell != 0));

foreach(var row in myMultiArray)
    foreach(var cell in myMultiArray)
        if(cell != 0)
            //Found it!

for(int i = 0; i < array.GetLength(0); i++)
    for(int j = 0; j < array.GetLength(1); j++)
         if(array[i,j] != 0)
             //Do Something
