C＃數組，字符串，錯誤

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刨做一個程序，如果我選擇一個城市，我得到第一排在B市，我得到2排

Answer 1

我認爲這是因爲市[I]「唐」牛逼包含任何」你應該檢查市[I，0]

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

Answer 2

我寧願做它作爲

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

Answer 3

你City變量並不需要是一個二維數組。如果將其更改爲一維數組，則可以使用一個索引而不是2來訪問這些值。

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