将字符串数组转换为int [] [英] converting a string array to int[]

问题描述

我有我的数组

string[]myNumber=new string[]{"1,2,5,4,6,"};

我如何将上述数组转换为:

int[]number=new int[]{1,2,5,4,6,};

请注意，我尝试使用myNumbers.CopyTo(number,0)，但失败，并出现系统警告，两个数组必须具有相同的类型和大小.

还是我可以使用其他任何方式，例如List<>来实现此功能.

我的目的是将string数组转换为int[]

在此先感谢
您的马丁

解决方案

尝试

string[] myNumber=new string[]{"1,2,5,4,6,"};
string[] arr = String.Split(myNumber[0]);
int[] intarr = new intarr[arr.count];
foreach(string str in arr)
{
   intarr[count++] = Convert.ToInt(str);
}

public int[] StringToInt(string[] arr)
{
int i;
List<int> result = new List<int>();
for(int x=0;x < arr.Length; x++)
{
    if (int.TryParse(arr[x], out i))
        result.Add(i);
}
return result.ToArray();
}
</int></int>

万一解析了无效的字符串，这将稍微安全些. ，5"... ...不是五个单独的字符串. :)

但是...这是一种实现方法...

 字符串 [] strValues = 新 "   1"，  2"，  3 "，  4"，  5"};
 int  [] intValues = strValues.Select(val = >  Convert.ToInt32(val)).ToArray (); 

hi there,I have my array

string[]myNumber=new string[]{"1,2,5,4,6,"};

how can i convert above array to:

int[]number=new int[]{1,2,5,4,6,};

Note that i have tried to use myNumbers.CopyTo(number,0),it failed with a system warning that the two array must be of the same type and size.

Or is there any other way i can use, like List<> to achieve this function.

My aim is to convert the string array to int[]

Thanks in advance
Yours Martin

解决方案

Try

string[] myNumber=new string[]{"1,2,5,4,6,"};
string[] arr = String.Split(myNumber[0]);
int[] intarr = new intarr[arr.count];
foreach(string str in arr)
{
   intarr[count++] = Convert.ToInt(str);
}

public int[] StringToInt(string[] arr)
{
int i;
List<int> result = new List<int>();
for(int x=0;x < arr.Length; x++)
{
    if (int.TryParse(arr[x], out i))
        result.Add(i);
}
return result.ToArray();
}
</int></int>

This will be just a little safer in case an invalid string is parsed in.

First, the way you intialized your string array, you created one string of "1,2,3,4,5" ... not five individual strings. :)

But... here is one way to do it...

string[] strValues = new string[] { "1", "2", "3", "4", "5" };
int[] intValues = strValues.Select(val => Convert.ToInt32(val)).ToArray();
