我怎样从c＃中读取整个数组 [英] How do I read from the entire array in c#

问题描述

我在这里有这个代码，我正在尝试读取数组的索引，我需要它来读取所有不一次只有一个



这是可能的？

I have this code here and I am trying to read the indexes of the array I need it to read all not just one at a time

Is this possible?

string s = textBox1.Text;

           string[] arr = new string[]
   {
       "cat",
       "dog",
       "panther",
       "tiger"
   };

          if (s.Contains(arr[0]))
           {
string v = s.Replace(arr[0], "*********");
              //show message with work that isnt allowed
              MessageBox.Show("Can not use the word " + arr[0]);
               textBox2.Text = v;
           }
           else
           {
               textBox2.Text = s;
           }

推荐答案

我会这样做。

string st = "Bob had a cat and a tiger";
           string[] arr = {
               "cat",
               "dog",
               "panther",
               "tiger"
           };
           foreach (var name in arr)
           {
               if (st.Contains(name))
               {
                   st = st.Replace(name, "****");
                   Console.WriteLine("Cannot use the word " + name);
               }

           }

           Console.WriteLine(st);//Bob had a **** and a ****

           //using linq
           st = "Bob had a dog and a panther";

               foreach (var name in arr.Where(name => st.Contains(name)))
               {
                   st = st.Replace(name, "****");
                   Console.WriteLine("Cannot use the word " + name);
               }
               Console.WriteLine(st);

            //using a StringBuilder with no 'where' clause
           st = "Bob had a dog and a panther";
           StringBuilder msb=new StringBuilder(st);

               foreach (var name in arr)
               {
                   msb.Replace(name, "****");
                   Console.WriteLine("Cannot use the word " + name);
               }
               Console.WriteLine(msb);

使用for循环阅读

use a for loop to read

for(int i = 0; i < arr.Length; i++){
 // arr[ i ]  do something here
}

数组和许多其他集合实现了一个迭代器接口，可以帮助遍历集合（或数组）。

以下是迭代这些数组的一些示例 -

如何：遍历数组 [ ^ ]

Arrays and many other collections implement an iterator interface that can help loop through the collection (or array).
