Answer 1

您可以使用lambda或LINQ来完成此操作。我提供了一个工作示例。

namespace ConsoleApplication1 
{ 
    using System; 
    using System.Collections.Generic; 
    using System.Linq; 

    class Program 
    { 
     static void Main(string[] args) 
     { 
      List<Container> table1 = new List<Container>() 
      { 
       new Container { Column1 = "Sam", Column2 = "Fred" }, 
       new Container { Column1 = "Arnold", Column2 = "Frank" } 
      }; 

      List<Container> table2 = new List<Container>() 
      { 
       new Container { Column1 = "Whitwicky", Column2 = "Flintstone" }, 
       new Container { Column1 = "Schwartz", Column2 = "Sinatra" } 
      }; 

      var result = Example.MergeTables(table1, table2); 

      foreach (var r in result) 
      { 
       Console.WriteLine(r.Column1 + "\t\t" + r.Column2); 
      } 

      Console.ReadLine(); 
     } 
    } 

    public class Example 
    { 
     public static IEnumerable<Container> MergeTables(List<Container> table1, List<Container> table2) 
     { 
      return table1.Select((value, index) => 
       new Container 
       { 
        Column1 = value.Column1 + " " + table2[index].Column1, 
        Column2 = value.Column2 + " " + table2[index].Column2 
       }); 

     } 
    } 

    public class Container 
    { 
     public string Column1 { get; set; } 
     public string Column2 { get; set; } 
    } 
}
