C＃数组，字符串，错误

Question

 int i; 
     int [,] Prices = new int [2, 7]{{1,2,3,4,5,6,7},{700,600,500,400,300,200,100}}; 
     string[,] City = new string [2,1]{{"A"},{"B"}}; 
     bool found = false; 
     for (i = 0; i <= City.Length -1; i++) 
      // for (y = 0; y <= City.Length - 1; y++) 


     { 
      if (LstDestinationCity.Text == City[i]) <<-- i get error here 
      { 

IM刨做一个程序，如果我选择一个城市，我得到第一排在B市，我得到2排

Answer 1

我认为这是因为市[I]“唐”牛逼包含任何”你应该检查市[I，0]

if (LstDestinationCity.Text == City[i,0])// this should access the first element which is the text you are looking for 

Answer 2

我宁愿做它作为

if (LstDestinationCity.Text == City[i,i]) 
{ 
    // ... 
} 

Answer 3

你City变量并不需要是一个二维数组。如果将其更改为一维数组，则可以使用一个索引而不是2来访问这些值。

string[] City = new string [2]{"A","B"};
