C#按值排序数组

问题描述

你好，

我有一个值列表

200000
90000
500000
60000
150000

我需要对它进行排序

60000
90000
150000
200000
500000

我正在使用ArrayList Sort并将其排序为

150000
200000
500000
60000
90000

Hi there,

I have a list of values

150000

I need to sort it

60000
90000

I am using an ArrayList Sort and it sorting it as

public void OrderDropDowns(ref DropDownList objDDL)
        {
            // ArrayList to keep text and value items within the specified Drop Down
            ArrayList text_list = new ArrayList();
            ArrayList value_list = new ArrayList();

            foreach (ListItem li in objDDL.Items)
            {
                if (li.Text != "-Select One-")
                {
                    text_list.Add(li.Text);
                }
            }
            if (text_list.Count >= 8)
            {
                text_list.Sort(0, 4, null);
            }
            else
            {
                text_list.Sort();
            }

            foreach (object li in text_list)
            {
                string value = objDDL.Items.FindByText(li.ToString()).Value;
                value_list.Add(value);
            }

            // Adding Sorted Items to the Drop Down List
            objDDL.Items.Clear();
            objDDL.Items.Add("-Select One-");
            for (int i = 0; i < text_list.Count; i++)
            {
                if (i != text_list.Count)
                {
                    ListItem objItem = new ListItem(text_list[i].ToString(), value_list[i].ToString());
                    objDDL.Items.Add(objItem);
                }
            }
        }

Any help would do please

推荐答案

int[] intArray = { 8, 10, 2, 6, 3 };

// Sort your int array
Array.Sort(intArray);
foreach (var i in intArray)
{
    Console.WriteLine(i);
}

// Sort it the other way
foreach (var i in intArray.Reverse())
{
    Console.WriteLine(i);
}

按属性订购对象:

order objects by property:

MyCollection.OrderBy(o => o.PropertyName);
MyCollection.OrderByDescending(o => o.PropertyName);

var sortedList = list.Cast<string>().OrderBy(item => int.Parse(item));
