编译单元使用解析的"For"/"Next"语句

我面临一个问题，当我创建一个虚拟的命名空间，类和子，并为for/Next循环添加解析语句时，它在我的编译单元的NormalizeWhitespace方法上崩溃。

IndexOutOfRangeException
Index was outside the bounds of the array.

下面是要复制的代码:

public void Main()
{
   var compilationUnit = SyntaxFactory.CompilationUnit();
   compilationUnit = compilationUnit.AddMembers(this.CreateNamespaceDeclaration());
   compilationUnit = compilationUnit.NormalizeWhitespace(true, "'r'n", false);
   compilationUnit.ToFullString().Dump();
}
public string[] StatementList = { "For i As Integer = 0 To 10", "Dim v = 0", "Next" };
// Define other methods and classes here
private NamespaceBlockSyntax CreateNamespaceDeclaration()
{
    return SyntaxFactory.NamespaceBlock(
        SyntaxFactory.NamespaceStatement(
        SyntaxFactory.IdentifierName("Test")))
        .WithMembers(
            SyntaxFactory.SingletonList<StatementSyntax>(
                SyntaxFactory.ClassBlock(
                SyntaxFactory.ClassStatement("VBCrash")
                .WithModifiers(
                    SyntaxFactory.TokenList(
                        SyntaxFactory.Token(SyntaxKind.PublicKeyword))))
        .WithImplements(SyntaxFactory.List<ImplementsStatementSyntax>())
        .WithMembers(SyntaxFactory.List<StatementSyntax>(
                SyntaxFactory.List<StatementSyntax>()
                .Add(SyntaxFactory.SubBlock(
                SyntaxFactory.SubStatement("Main"))
            .AddStatements(this.AddStatements()))))));
}

private StatementSyntax[] AddStatements()
{
    var result = default(SyntaxList<StatementSyntax>);
    foreach (var statement in StatementList)
    {
        result = result.Add(SyntaxFactory.ParseExecutableStatement(statement));
    }
    return result.ToArray();
}

我做错了什么吗?每当我为语句注释foreach循环时，它就会工作。

谢谢你的帮助
