问题描述

Dictionary<string,double> dic = new Dictionary<string, double>();
         dic.Add("Stuend 1",80);
         dic.Add("Stuend 2", 70);
         dic.Add("Stuend 3", 40.7);
         dic.Add("Stuend 4", 50);
         dic.Add("Stuend 5",22);
         dic.Add("Stuend 6", 100);

I want to need Student Key name who get the mark is minimum.
May i know how to wiite with Linq.

推荐答案

尝试一下:

Try this:

var maxValue = dic[dic.Keys.Max()];

请参考一些示例链接:

以下方法在序列的每个元素上调用转换函数，并返回最大Int32 值:
Enumerable.Max< tsource>方法(IEnumerable< tsource>，Func< tsource>) [ ^ ]
此方法以可为空的Double 值序列返回最大值.可枚举.Max方法(IEnumerable< nullable>< double>>) [ ^ ]

另请参阅:
可枚举 [原型可枚举的max()方法 [ max()公共 [ ^ ]

Please refer some links for examples:

The following method invokes a transform function on each element of a sequence and returns the maximum Int32 value:
Enumerable.Max<tsource> Method (IEnumerable<tsource>, Func<tsource,>)[^]
This method returns the maximum value in a sequence of nullable Double values.Enumerable.Max Method (IEnumerable<nullable><double>>)[^]

Also refer:
Enumerable[^]
Prototype Enumerable max() Method[^]
max() public[^]

由于这听起来像是作业，因此建议您从这里开始frm:Enumerable.Max方法 [

Since this sounds like homework, I''d suggest that you start for example frm here: Enumerable.Max Method [^]
