“像使用一种类型的命名空间”错误 [英] 'namespace used like a type' error

问题描述

codeRS，我想转换一个XAML字符串中使用的库，我发现的此处，但我有创造，将让我使用的库对象的新实例的问题。我已经添加了一个参考图书馆在我的Asp.net项目，我想用它在一个WCF文件。

现在的问题是，每当我尝试实例化一个新的对象，使用new关键字，我得到一个错误，说：

  

MarkupConverter'是'空间'，但用于像一个类型。

下面是我的code，请注意，我创造就像在上面的库链接显示的例子一个新的对象，请帮助：

 使用系统;
使用System.Collections.Generic;
使用System.Linq的;
使用System.Runtime.Serialization;
使用System.ServiceModel;
使用System.Text;
使用System.Web.Services;
使用System.Net.Mail;
使用System.ServiceModel.Activati​​on;
使用System.Data.SqlClient的;
使用MarkupConverter;

命名空间AspPersonalWebsite
{
    [的ServiceContract（命名空间=）]
    [AspNetCompatibilityRequirements（RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed）
    公共类服务1 //：IService1
    {
        私人字符串的connectionString = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString;
        私人IMarkupConverter markupConverter;

        [OperationContract的]
        公共字符串convertXAMLToHTML（字符串XAMLtext）
        {
            字符串的htmlText =;
            markupConverter =新MarkupConverter（）; / *问题是在这里* /
            的htmlText = markupConverter.ConvertXamlToHtml（XAMLtext）;
            返回的htmlText;
        }
    }
}
 

解决方案

混乱是因为所产生的实际类型是 MarkupConverter.MarkupConverter ，编译器似乎认为你的新MarkupConverter 是试图使用一个命名空间作为一个类型，而不是试图实例化一个类型的使用命名空间中。

只需将您的问题行更改为：

  markupConverter =新MarkupConverter.MarkupConverter（）; / *这里的解决方案！* /
 

......，你应该罚款。

Coders, I am trying to convert a XAML string to HTML using a library I found here , but I have a problem with creating a new instance of the object that would let me use the library. I already added a reference to the library in my Asp.net project and I would like to use it in a WCF file.

The problem is that whenever I try to instantiate a new object with the new keyword, I get an error that says:

'MarkupConverter' is a 'namespace' but is used like a 'type'.

Here is my code, notice that I am creating a new object just like the example shown in the library link above, please help:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.Web.Services;
using System.Net.Mail;
using System.ServiceModel.Activation;
using System.Data.SqlClient;
using MarkupConverter;

namespace AspPersonalWebsite
{
    [ServiceContract(Namespace = "")]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Service1 //: IService1
    {
        private string connectionString = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString;
        private IMarkupConverter markupConverter;        

        [OperationContract]
        public string convertXAMLToHTML(string XAMLtext)
        {
            string htmlText = "";
            markupConverter = new MarkupConverter(); /*PROBLEM IS HERE*/
            htmlText = markupConverter.ConvertXamlToHtml(XAMLtext);
            return htmlText;
        }
    }
}

解决方案

Confusion is arising because the actual type is MarkupConverter.MarkupConverter, the compiler seems to think your new MarkupConverter is an attempt to use a namespace as a type, rather than an attempt to instantiate a type inside your using namespace.

Simply change your problem line to:

markupConverter = new MarkupConverter.MarkupConverter(); /*SOLUTION HERE!*/

..and you should be fine.
