C#配列ソートの2つの一般的な方法

この例では、C#配列ソートの2つの一般的な方法について説明します.皆さんの参考にしてください.具体的には以下の通りです.
1.第一例
定義コード

#region Array    1
public class Pigeon : IComparable
//           
{
int XValue;
int YValue;
public string BatchNo { get; set; }
public int CompareTo(Pigeon other)
{
  if (other == null)
 throw new ArgumentNullException("      ");
  //        
  XValue = Convert.ToInt32(this.BatchNo.Substring(2, 1));
  YValue = Convert.ToInt32(other.BatchNo.Substring(2, 1));
  if (XValue == YValue)
  {
 return 0;
  }
  else if (XValue < YValue)
  {
 return -1;   //  -1,X  Y   
  }
  else
  {
 return 1;    //  1,X  Y   
  }
}
}
#endregion

テストコード

#region   Array    1
private void button3_Click(object sender, EventArgs e)
{
  Pigeon[] pigeons = new Pigeon[]{
 new Pigeon(){BatchNo="1256"},
 new Pigeon(){BatchNo="1236"},
 new Pigeon(){BatchNo="1276"},
 new Pigeon(){BatchNo="1216"}
  };
  Array.Sort(pigeons);
  string ResultMsg = "";
  foreach (Pigeon o in pigeons)
  {
 ResultMsg += o.BatchNo + "\r
";
  }
  MessageBox.Show(ResultMsg);
}
#endregion

1.第2例
定義コード

#region Array

public string BatchNo { get; set; }
}

FourChar=1
}

//

public MyBatchCompare(CompareType compareType)
{
  //            
  this.compareType = compareType;
}
public int Compare(MyBatch x, MyBatch y)
{
  int XValue;
  int YValue;
  if (x == null) throw new ArgumentNullException("x   ");
  if (y == null) throw new ArgumentNullException("y   ");
  switch (compareType)
  {          
 case CompareType.ThreeChar:
   //              
   XValue = Convert.ToInt32(x.BatchNo.Substring(2,1));
   YValue = Convert.ToInt32(y.BatchNo.Substring(2,1));
   if (XValue == YValue)
   {
 return 0;
   }
   else if (XValue < YValue)
   {
 return -1;   //  -1,X  Y   
   }
   else
   {
 return 1;    //  1,X  Y   
   }
 case CompareType.FourChar:
   //              
   XValue = Convert.ToInt32(x.BatchNo.Substring(3,1));
   YValue = Convert.ToInt32(y.BatchNo.Substring(3,1));
   if (XValue == YValue)
   {
 return 0;
   }
   else if (XValue < YValue)
   {
 return -1;   //  -1,X  Y   
   }
   else
   {
 return 1;    //  1,X  Y   
   }
 default:
   throw new ArgumentException("        ");
  }
}
}
#endregion
