c# - 写this.propertyName或只是propertyName之间的区别

Question

我正在看一个编写类并使用构造函数的示例，并想知道使用“ this”的区别是什么。或不。

那么，两者之间有什么区别？

public class PagedCountryList
{
    public IEnumerable<Country> CountriesToDisplay { get; set; }
    public int Total { get; set; }
    public int PerPage { get; set; }
    public int PageNumber { get; set; }

    public PagedCountryList(IEnumerable<Country> countries, int totalResult, int elementsPerPage, int pageNumber)
    {
        this.CountriesToDisplay = countries;
        this.Total = totalResult;
        this.PerPage = elementsPerPage;
        this.PageNumber = pageNumber;
    }
}

和这个：

public class PagedCountryList
{
    public IEnumerable<Country> CountriesToDisplay { get; set; }
    public int Total { get; set; }
    public int PerPage { get; set; }
    public int PageNumber { get; set; }

    public PagedCountryList(IEnumerable<Country> countries, int totalResult, int elementsPerPage, int pageNumber)
    {
        CountriesToDisplay = countries;
        Total = totalResult;
        PerPage = elementsPerPage;
        PageNumber = pageNumber;
    }
}

Answer 1

您的情况没有区别，但请考虑以下示例

public class PagedCountryList
{
    private IEnumerable<Country> countries { get; set; }
    public int totalResult { get; set; }
    public int elementsPerPage { get; set; }
    public int pageNumber { get; set; }

    public PagedCountryList(IEnumerable<Country> countries, int totalResult, int elementsPerPage, int pageNumber)
    {
       //you cant write something like this (because it is ambiguous)
       //countries = countries;
        this.countries = countries;
        this.totalResult = totalResult;
        this.elementsPerPage = elementsPerPage;
        this.pageNumber = pageNumber;
    }
}
