在字典列表中为每个循环定义两个单独的变量

Question

到目前为止，这是我的代码，我很难定义字符串和UInt32从列表数组中选择的每个循环。谁能告诉我如何克服这个问题？

 Dictionary<string, UInt32> cars = new Dictionary<string, UInt32>();

 cars.Add("Vehicle1", 4294967295);
 cars.Add("Vehicle2", 6329496762);

 foreach (KeyValuePair<string, UInt32> pair in cars)
 {
     string vehiclename = pair.Item1; 
     UInt32 vehicledata = pair.Item2;   
 }

Answer 1

正确的语法是

 // You have to switch to long from UInt32 since... 
 Dictionary<string, long> cars = new Dictionary<string, long>();

 cars.Add("Vehicle1", 4294967295L);
 cars.Add("Vehicle2", 6329496762L); // ... this value is greater than UInt32.MaxValue

 // var: you have no need to put such a long declaration as KeyValuePair<string, long>
 foreach (var pair in cars)
 {
     string vehiclename = pair.Key; 
     long vehicledata = pair.Value;   
 }

请注意，KeyValuePair
