GetCustomFunctionEnumerator メソッド (ICustomFunctionSupport)

モデル内のユーザー定義関数の名前を列挙するIEnumeratorを取得します。

構文

Visual Basic
C#

'Declaration
 
Function GetCustomFunctionEnumerator() As IEnumerator

'使用法
 
Dim instance As ICustomFunctionSupport
Dim value As IEnumerator
 
value = instance.GetCustomFunctionEnumerator()

IEnumerator GetCustomFunctionEnumerator()

戻り値の型

カスタム関数の列挙子を含む IEnumerator

例

次のサンプルコードは、ユーザー定義のカスタム関数（Functionオブジェクト）の名前を列挙するIEnumeratorを返します。

public class CubeFunctionInfo : FarPoint.CalcEngine.FunctionInfo
    {
      public override string Name { get { return "CUBE"; } }
      public override int MinArgs { get { return 1; } }
      public override int MaxArgs { get { return 1; } }
      public override object Evaluate (object[] args)
      {
        double num = FarPoint.CalcEngine.CalcConvert.ToDouble(args[0]);
        return num * num * num;
      }
    }

public class MultiFunc : FarPoint.CalcEngine.FunctionInfo
    {
      public override string Name { get { return "MULTI"; } }
      public override int MinArgs { get { return 1; } }
      public override int MaxArgs { get { return 1; } }
      public override object Evaluate (object[] args)
      {
        double num = FarPoint.CalcEngine.CalcConvert.ToDouble(args[0]);
        return num * num;
      }
    }

FarPoint.Win.Spread.Model.ICustomFunctionSupport cfs;
System.Collections.IEnumerator se;
cfs = (FarPoint.Win.Spread.Model.ICustomFunctionSupport)fpSpread1.ActiveSheet.Models.Data;
cfs.AddCustomFunction(new CubeFunctionInfo());
cfs.AddCustomFunction(new MultiFunc());
fpSpread1.ActiveSheet.SetFormula(1, 1, "CUBE(4)");
fpSpread1.ActiveSheet.SetFormula(2, 2, "MULTI(10)");
se = cfs.GetCustomFunctionEnumerator();
listBox1.Items.AddRange(new Object[] {se.MoveNext().ToString(), se.Current.ToString(), se.MoveNext().ToString(), se.Current.ToString()});
