c＃他のクラスメソッドを使用

Question

NHMountainGoatのおかげで答えが得られました！ インタフェースを実装するのが良い選択肢に見えるので、「必要な」メソッドのみがインスタンス化されています。 それは次のようになります。 EDIT

class Machine 
{ 
    //REM: MachineConnexion is a link to the main server where asking the data 
    internal linkToPLC LinkToPLC; 
    public IlinkToPLC ILinkPLC; 
    public interface IlinkToPLC//Interface to linkPLC 
    { 
     Int16 MachineNumIS { get; set; } 
    } 
    internal class linkToPLC : IlinkToPLC 
    { 
     private Int16 Act_MachineNum; 
     private List<string> genlnkPLCCanvas; 
     private List<string> genlnkPLCworkingwith; 
     static private List<string> ListSymbolNoExist; 
     private string[] ListToPLClnk = { 
          "GlobalFolder.PMachine[{0}].", 
          "GlobalFolder.PMachine[{0}].STATE.", 
          "GlobalFolder.Machine[{0}].", 
          "GlobalFolder.Machine[{0}].STATE.", 
         }; 
     public linkToPLC()//ctor 
     { 
      genlnkPLCCanvas = new List<string>(ListToPLClnk); 
      genlnkPLCworkingwith = new List<string>(ListToPLClnk); 
      ListSymbolNoExist = new List<string>(); 
      Act_MachineNum = MachineNumIS; 
     } 
     public Int16 MachineNumIS { get { return (Int16)ReadWriteMachine("data"); } set { ReadWriteMachine("data", value); } } 
     public string ValueExist(string ValueToreach, bool WorkingDATA = false) 
     { 
      if (!WorkingDATA) 
      { 
       for (int inc = 0; inc < genlnkPLCworkingwith.Count; inc++) 
       { 
        string StrValueToReach = genlnkPLCworkingwith[inc] + ValueToreach; 
        if (MachineConnexion.SymbolExists(StrValueToReach)) 
        { 
         ListSymbolNoExist.Clear(); 
         return StrValueToReach; 
        } 
        else ListSymbolNoExist.Add(genlnkPLCworkingwith[inc] + ValueToreach); 
       } 
      } 
      else if (WorkingDATA) 
      { 
       string StrValueToReach = genlnkPLCworkingwith[10] + ValueToreach; 
       if (MachineConnexion.SymbolExists(StrValueToReach)) 
       { 
        ListSymbolNoExist.Clear(); 
        return StrValueToReach; 
       } 
       else ListSymbolNoExist.Add(genlnkPLCworkingwith[10] + ValueToreach); 
      } 
      if (ListSymbolNoExist.Count != 0) 
      { 
       string ErrorList = ""; 
       for (int inc = 0; inc < ListSymbolNoExist.Count; inc++) 
       { 
        ErrorList = string.Concat(ErrorList + "Num: " + inc.ToString() + " " + ListSymbolNoExist[inc].ToString() + "\n"); 
       } 
       Console.WriteLine("Error" + ErrorList); 
      } 
      return null; 
     } 
     public object ReadWriteMachine(string VariableName, object DataToWrite = null, bool WorkingDATA = false) 
     { 
      string valueToFind = ""; 
      if (ValueExist(VariableName) != "FALSE") 
      { 
       if (DataToWrite != null) { MachineConnexion.WriteSymbol(valueToFind, DataToWrite); } 
       return MachineConnexion.ReadSymbol(valueToFind); 
      } 
      return VariableName; 
     } 
    } 
    public Machine()     //constructor 
    { 
     LinkToPLC = new linkToPLC(); 
    } 
} 

、それはラインで.....参照オブジェクトがオブジェクトのインスタンスに定義されていないことを私に言っては動作しません：マシン（）LinkToPLC =新しいlinkToPLC（）;私はバグを見つけ// REMは、それは私だった; O））24112016

// REM 24112016

これら二つの概念の主な違いは何ですか：静的インスタンスおよびインターフェイスは？

例：

class Program 
{ 
    static void Main(string[] args) 
    { 
     ITestInterface InterInstance = new TestInterface(); 
     //test Interface 
     bool value1 = true; 
     value1 = InterInstance.invert(value1); 
     InterInstance.print(value1); 
     //test Instance static 
     TestStaticInstance staticInstance = new TestStaticInstance(); 
     staticInstance.Instance.invert(value1); 
     staticInstance.Instance.print(value1); 
     Console.ReadKey(); 
    } 
} 
class TestInterface : ITestInterface 
{ 
    public bool invert(bool value) 
    { 
     return !value; 
    } 
    public void print(bool value) 
    { 
    Console.WriteLine(value.ToString()+"\n"); 
    } 
    private void methodX() 
    { } 
} 
interface ITestInterface 
{ 
    bool invert(bool value); 
    void print(bool value); 
} 
public class TestStaticInstance 
{ 
    public TestStaticInstance Instance; 
    public TestStaticInstance() 
    { 
     Instance = this; 
    } 
    internal bool invert(bool value) 
    { 
     return !value; 
    } 
    internal void print(bool value) 
    { 
     Console.WriteLine(value.ToString()); 
    } 
} 

おかげ

あなたはリンククラスのインスタンスを取るために、あなたの他のクラスを構築することはできますか？参照：
