如何用連續值初始化列表<type>？

Question

我有這樣

public class Sample 
{ 
    public string A { get; set; } 
    public int B { get; set; } 
} 

var sampleValues = new List<Sample>(){ 
     new Sample(){ A = "a1", B = 1 }, 
     new Sample(){ A = "a2", B = 2 }, 
     new Sample(){ A = "a3", B = 3 }, 
     new Sample(){ A = "a4", B = 4 }, 
     ..... 
     new Sample(){ A ="a30", B = 30} 
    }; 

類是有連續用30個值初始化它的任何簡單的方法如圖所示？

Answer 1

使用Enumerable.Range，如：

List<Sample> samvalues = Enumerable.Range(1, 30) 
           .Select(r => new Sample {A = "a" + r, B = r}) 
           .ToList(); 

或者

List<Sample> samvalues = Enumerable.Range(1, 30) 
        .Select(r => new Sample {A = String.Format("{0}{1}", "a", r), B = r}) 
        .ToList();
