在C#中列出GetRange错误 [英] List GetRange error in C#

问题描述

我正在处理列表，我的列表有14条记录.

i am working with list and my list has 14 record.

 List<Product> oProduct = new List<Product> 
        {
           new Product("../images/1.jpg", "Sample Data.1"),
           new Product("../images/2.jpg", "Sample Data.2"),
           new Product("../images/3.jpg", "Sample Data.3"),
           new Product("../images/4.jpg", "Sample Data.4"),
           new Product("../images/5.jpg", "Sample Data.5"),
           new Product("../images/6.jpg", "Sample Data.6"),
           new Product("../images/7.jpg", "Sample Data.7"),
           new Product("../images/8.jpg", "Sample Data.8"),
           new Product("../images/9.jpg", "Sample Data.9"),
           new Product("../images/10.jpg", "Sample Data.10"),
           new Product("../images/11.jpg", "Sample Data.11"),
           new Product("../images/12.jpg", "Sample Data.12"),
           new Product("../images/13.jpg", "Sample Data.13"),
           new Product("../images/14.jpg", "Sample Data.14"),
        };

当我将以下行用于getrange时，我的索引超出了范围错误.

when i use the below line for getrange then i am getting index out of bound error.

List<Product> xProduct = oProduct.GetRange(10, 13);

但是我的列表中有14个元素，那么为什么我不能从第10位到第14位提取数据....请指导谢谢.

but my list has 14 element then why i can not extract data from 10th position to 14th position....please guide thanks.

推荐答案

The second parameter to GetRange needs to be the count of elements to get, so change it to 4 (I think that's what you want).

此外，第一个参数是基于零的索引，因此您希望 GetRange(9，4)获取10到13的图像.

Also, the first parameter is the zero-based index, so you want GetRange(9, 4) to get images 10 through 13.
