解説

CodeMemberField を使用して、型のフィールドの宣言を表すことができます。

使用例

CodeMemberField を使用して、型が string の testStringField という名前のフィールドを宣言する例を次に示します。

' Declares a type to contain a field and a constructor method.
Dim type1 As New CodeTypeDeclaration("FieldTest")

' Declares a field of type String named testStringField.
Dim field1 As New CodeMemberField("System.String", "testStringField")
type1.Members.Add(field1)

' Declares an empty type constructor.
Dim constructor1 As New CodeConstructor()
constructor1.Attributes = MemberAttributes.Public
type1.Members.Add(constructor1)

' A Visual Basic code generator produces the following source code for the preceeding example code:

' Public Class FieldTest
'
'     Private TestStringField As String
'
'     Public Sub New()
'         MyBase.New()
'     End Sub
'
' End Class

// Declares a type to contain a field and a constructor method.
CodeTypeDeclaration type1 = new CodeTypeDeclaration("FieldTest");

// Declares a field of type String named testStringField.
CodeMemberField field1 = new CodeMemberField("System.String", "TestStringField");
type1.Members.Add( field1 );

// Declares an empty type constructor.
CodeConstructor constructor1 = new CodeConstructor();
constructor1.Attributes = MemberAttributes.Public;            
type1.Members.Add( constructor1 );

// A C# code generator produces the following source code for the preceeding example code:

//    public class FieldTest 
//    {
//      private string testStringField;
//        
//        public FieldTest() 
//        {
//        }                            
//    }            

// Declares a type to contain a field and a constructor method.
CodeTypeDeclaration^ type1 = gcnew CodeTypeDeclaration( "FieldTest" );

// Declares a field of type String named testStringField.
CodeMemberField^ field1 = gcnew CodeMemberField( "System.String","TestStringField" );
type1->Members->Add( field1 );

// Declares an empty type constructor.
CodeConstructor^ constructor1 = gcnew CodeConstructor;
constructor1->Attributes = MemberAttributes::Public;
type1->Members->Add( constructor1 );

// A C# code generator produces the following source code for the preceeding example code:
//    public class FieldTest 
//    {
//      private string testStringField;
//        
//        public FieldTest() 
//        {
//        }                            
//    }            

// Declares a type to contain a field and a constructor method.
CodeTypeDeclaration type1 = new CodeTypeDeclaration("FieldTest");
// Declares a field of type String named testStringField.
CodeMemberField field1 = new CodeMemberField("System.String",
    "TestStringField");
type1.get_Members().Add(field1);
// Declares an empty type constructor.
CodeConstructor constructor1 = new CodeConstructor();
constructor1.set_Attributes(MemberAttributes.Public);
type1.get_Members().Add(constructor1);
// A VJ# code generator produces the following source code for the 
// preceeding example code:
//    public class FieldTest 
//    {
//        private String testStringField;
//        
//        public FieldTest() 
//        {
//        } //FieldTest                            
//    } //FieldTest           

' This example demonstrates declaring a public constant type member field.
' When declaring a public constant type member field, you must set a particular
' access and scope mask to the member attributes of the field in order for the
' code generator to properly generate the field as a constant field.
' Declares an integer field using a CodeMemberField
Dim constPublicField As New CodeMemberField(GetType(Integer), "testConstPublicField")

' Resets the access and scope mask bit flags of the member attributes of the field
' before setting the member attributes of the field to public and constant.
constPublicField.Attributes = constPublicField.Attributes And Not MemberAttributes.AccessMask And Not MemberAttributes.ScopeMask Or MemberAttributes.Public Or MemberAttributes.Const

// This example demonstrates declaring a public constant type member field.

// When declaring a public constant type member field, you must set a particular

CodeMemberField constPublicField = new CodeMemberField(typeof(int), "testConstPublicField");

// Resets the access and scope mask bit flags of the member attributes of the field
// before setting the member attributes of the field to public and constant.
constPublicField.Attributes = (constPublicField.Attributes & ~MemberAttributes.AccessMask & ~MemberAttributes.ScopeMask) | MemberAttributes.Public | MemberAttributes.Const;

// Resets the access and scope mask bit flags of the member attributes of the field

constPublicField->Attributes = (MemberAttributes)((constPublicField->Attributes &  ~MemberAttributes::AccessMask &  ~MemberAttributes::ScopeMask) | MemberAttributes::Public | MemberAttributes::Const);
