c# - 为什么 Roslyn 生成的方法代码没有空格

Question

Roslyn 生成的代码在标识符和关键字之间没有任何空格，我做错了什么？它还在方法 block 的末尾放置了一个分号。 这是我的代码:

SeparatedSyntaxList<ParameterSyntax> parametersList = new SeparatedSyntaxList<ParameterSyntax>().AddRange
(new ParameterSyntax[]
    {
        SyntaxFactory.Parameter(SyntaxFactory.Identifier("sender")).WithType(SyntaxFactory.ParseTypeName("object")),
        SyntaxFactory.Parameter(SyntaxFactory.Identifier("args")).WithType(SyntaxFactory.ParseTypeName("EventArgs"))
    }
);

MethodDeclarationSyntax newMethod = SyntaxFactory.MethodDeclaration(
    SyntaxFactory.List<AttributeListSyntax>(),
    SyntaxFactory.TokenList(SyntaxFactory.Token(SyntaxKind.PrivateKeyword)),
    SyntaxFactory.ParseName("void"),
    null,
    SyntaxFactory.Identifier("simpleButton1_Click"),
    null,
    SyntaxFactory.ParameterList(parametersList),
    SyntaxFactory.List<TypeParameterConstraintClauseSyntax>(),
    SyntaxFactory.Block(),
    SyntaxFactory.Token(SyntaxKind.SemicolonToken)
);

这是我得到的结果:

privatevoidsimpleButton1_Click(objectsender,EventArgse){};

为了更加全面，NormalizeWhiteSpace应该提到。它将默认格式应用于给定节点:

MethodDeclarationSyntax newMethod = SyntaxFactory.MethodDeclaration(
    SyntaxFactory.List<AttributeListSyntax>(),
    SyntaxFactory.TokenList(SyntaxFactory.Token(SyntaxKind.PrivateKeyword)),
    SyntaxFactory.PredefinedType(SyntaxFactory.Token(SyntaxKind.VoidKeyword)),
    null,
    SyntaxFactory.Identifier("simpleButton1_Click"),
    null,
    SyntaxFactory.ParameterList(parametersList),
    SyntaxFactory.List<TypeParameterConstraintClauseSyntax>(),
    SyntaxFactory.Block(),
    null
  )

newMethod = newMethod.NormalizeWhitespace();

ToString() 将产生预期的输出:

private void simpleButton1_Click(object sender, EventArgs args)
{
}
