字符串数组类型的方法返回类型错误 [英] String Array type method return type error

问题描述

public String[][] GetAllItems() 
    {
        FoodCityData.ShoppingBuddyEntities fdContext = new FoodCityData.ShoppingBuddyEntities();

        IQueryable<Item> Query =
       from c in fdContext.Item
       select c;

        List<Item> AllfNames = Query.ToList();
        int arrayZise = AllfNames.Count;
        String[,] xx = new String[arrayZise,2];
        int i = 0;
        int j = 0;
        foreach(Item x in AllfNames)
        {

                xx[i,0] = x.ItemName.ToString();
                xx[i, 1] = x.ItemPrice.ToString();
                i++;

        }

        return xx[2,2];  // how do i write return type?
    }

推荐答案

您有铁血阵列返回类型，你需要返回二维的 Rrectangular阵列，您可以返回这样的二维数组。

You have Jagged Array return type and you need to return two dimensional Rrectangular Array, You can return two dimensional array like this.

public String[,] GetAllItems() 
{
    //your code 
    String[,] xx = new String[arrayZise,2];
    //your code 
    return xx;    
}
