C#の単純なコードをC ++ / CLIに変換しようとしていますが、変換されたコードをビルドしようとすると、次のエラーが発生します。

そして、私のコードは次のとおりです。
// AST.cs
using namespace System;
/* <stmt> := var <ident> = <expr>
| <ident> = <expr>
| for <ident> = <expr> to <expr> do <stmt> end
| read_int <ident>
| print <expr>
| <stmt> ; <stmt>
*/
public ref class Stmt abstract
{
};
// var <ident> = <expr>
public ref class DeclareVar : Stmt
{
public:
String^ Ident;
Expr^ expr;
};
// print <expr>
public ref class Print : Stmt
{
public:
Expr^ Expr;
};
// <ident> = <expr>
public ref class Assign : Stmt
{
public:
String^ Ident;
Expr^ Expr;
};
// for <ident> = <expr> to <expr> do <stmt> end
public ref class ForLoop : Stmt
{
public:
String^ Ident;
Expr^ From;
Expr^ To;
Stmt^ Body;
};
// read_int <ident>
public ref class ReadInt : Stmt
{
public:
String^ Ident;
};
// <stmt> ; <stmt>
public ref class Sequence : Stmt
{
public:
Stmt^ First;
Stmt^ Second;
};
/* <expr> := <string>
* | <int>
* | <arith_expr>
* | <ident>
*/
public ref class Expr abstract
{
};
// <string> := " <string_elem>* "
public ref class StringLiteral : Expr
{
public:
String^ Value;
};
// <int> := <digit>+
public ref class IntLiteral : Expr
{
public:
int Value;
};
// <ident> := <char> <ident_rest>*
// <ident_rest> := <char> | <digit>
public ref class Variable : Expr
{
public:
String^ Ident;
};
// <bin_expr> := <expr> <bin_op> <expr>
public ref class BinExpr : Expr
{
public:
Expr^ Left;
Expr^ Right;
BinOp Op;
};
// <bin_op> := + | - | * | /
public enum class BinOp
{
Add,
Sub,
Mul,
Div
};
このコードは、次のコードから変換されます。
// AST.cs
/* <stmt> := var <ident> = <expr>
| <ident> = <expr>
| for <ident> = <expr> to <expr> do <stmt> end
| read_int <ident>
| print <expr>
| <stmt> ; <stmt>
*/
public abstract class Stmt
{
}
// var <ident> = <expr>
public class DeclareVar : Stmt
{
public string Ident;
public Expr Expr;
}
// print <expr>
public class Print : Stmt
{
public Expr Expr;
}
// <ident> = <expr>
public class Assign : Stmt
{
public string Ident;
public Expr Expr;
}
// for <ident> = <expr> to <expr> do <stmt> end
public class ForLoop : Stmt
{
public string Ident;
public Expr From;
public Expr To;
public Stmt Body;
}
// read_int <ident>
public class ReadInt : Stmt
{
public string Ident;
}
// <stmt> ; <stmt>
public class Sequence : Stmt
{
public Stmt First;
public Stmt Second;
}
/* <expr> := <string>
* | <int>
* | <arith_expr>
* | <ident>
*/
public abstract class Expr
{
}
// <string> := " <string_elem>* "
public class StringLiteral : Expr
{
public string Value;
}
// <int> := <digit>+
public class IntLiteral : Expr
{
public int Value;
}
// <ident> := <char> <ident_rest>*
// <ident_rest> := <char> | <digit>
public class Variable : Expr
{
public string Ident;
}
// <bin_expr> := <expr> <bin_op> <expr>
public class BinExpr : Expr
{
public Expr Left;
public Expr Right;
public BinOp Op;
}
// <bin_op> := + | - | * | /
public enum BinOp
{
Add,
Sub,
Mul,
Div
}
わかりました、どうすればこのエラーを修正できますか?(私にとって、コードは正しいからです。。。。)
