Question

我似乎无法排序，因为它只排序第一个数字

int storageCapacity;

IEnumerable<ProductStorageCapacity> items;

if (int.TryParse(filter["StorageCapacity"], out storageCapacity) && storageCapacity > 0)
     items = await context.ProductStorageCapacities
     .Where(ps => ps.StorageCapacity == storageCapacity)
     .OrderByDescending(ps => ps.StorageCapacity).ToListAsync();
else items = await context.ProductStorageCapacities
     .OrderBy(ps => ps.StorageCapacity).ToListAsync();

任何帮助？

Answer 1

在某处，你的StorageCapacity是一个字符串。

查看此代码（实例：http://rextester.com/NZALE31796）：

var intList = new []{0,500,1000};
var strList = new []{ "0", "500", "1000"};


Console.WriteLine(String.Join(",",intList.OrderByDescending(x => x)));
Console.WriteLine(String.Join(",",strList.OrderByDescending(x => x)));

输出结果为：

1000,500,0
500,1000,0

第一个结果是你期望订购ints降序。第二个是从相同的字符串输入中获得的。

Linq只按第一位数排序
