WebHandler ASHX .NET編譯器錯誤：必須實現與ReadOnly/WriteOnly相匹配的IsReusable

Question

大約8年前，我已經被委託給一個用VB.NET/ASP.NET編寫的遺留網站添加一個web處理程序，使用.NET框架1.1.4322。

我不明白爲什麼我收到此錯誤信息：

Compiler Error Message: BC30154: 'Foo' must implement 'Overridable ReadOnly Property IsReusable() as Boolean' for interface 'System.Web.IHttpHandler'. Implementing property must have matching 'ReadOnly/WriteOnly' specifiers

這裏是我的代碼：

<%@ WebHandler language="VB" class="Foo" %> 
Imports System 
Imports System.Web 

Public Class Foo 
Implements IHttpHandler 

Public Sub ProcessRequest(context as HttpContext) 
    Implements IHttpHandler.ProcessRequest 
    'TO DO: Write request handling code here 
End Sub 

Public ReadOnly Property IsReusable() as Boolean 
Implements IHttpHandler.IsReusable 
    Get 
    Return False 
    End Get 
End Property 

End Class 

我也試過ReadOnly Overrides Property IsReusable()。

您需要將IsReusable屬性標記爲Overridable而不是Overrides。
