定義

取得或設定目前 HTTP 要求的 HttpContext 物件。Gets or sets the HttpContext object for the current HTTP request.

public:
 static property System::Web::HttpContext ^ Current { System::Web::HttpContext ^ get(); void set(System::Web::HttpContext ^ value); };
public static System.Web.HttpContext Current { get; set; }
member this.Current : System.Web.HttpContext with get, set
Public Shared Property Current As HttpContext

屬性值

目前 HTTP 要求的 HttpContext 執行個體。The HttpContext instance for the current HTTP request.

範例

下列程式碼範例會使用Current屬性來HttpContext.AddError存取和HttpContext.ClearError方法, 以及HttpContext.AllErrors屬性。The following code example uses the Current property to access the HttpContext.AddError and HttpContext.ClearError methods and the HttpContext.AllErrors property. 此範例會使用AddError方法來建立三個自訂例外狀況, 並AllErrors使用屬性將這些例外狀況載入陣列。The example creates three custom exceptions using the AddError method and uses the AllErrors property to load these exceptions to an array. 然後, 它會將陣列寫入包含的頁面, 並ClearError使用方法來清除Context屬性中的所有錯誤。It then writes the array to the containing page and uses the ClearError method to clear all the errors from the Context property.

protected void Page_Load(object sender, EventArgs e)  
{  
    HttpContext context = HttpContext.Current;  
    Response.Write("<p>HttpContext.Current Example:</p>");  

    // Add three custom exceptions.  
    context.AddError(new Exception("New Exception #1"));  
    context.AddError(new Exception("New Exception #2"));  
    context.AddError(new Exception("New Exception #3"));  

    // Capture all the new Exceptions in an array.  
    Exception[] errs = context.AllErrors;  

    foreach (Exception ex in errs)  
    {  
        Response.Write("<p>" + Server.HtmlEncode(ex.ToString()) + "</p>");  
    }  

    // Clear the exceptions so ASP.NET won't handle them.  
    context.ClearError();  
}  
Protected Sub Page_Load(sender As Object, e As EventArgs)  
Dim context As HttpContext = HttpContext.Current  
Response.Write("<p>HttpContext.Current Example:</p>")  

' Add three custom exceptions.  
context.AddError(New Exception("New Exception #1"))  
context.AddError(New Exception("New Exception #2"))  
context.AddError(New Exception("New Exception #3"))  

' Capture all the new Exceptions in an array.  
Dim errs As Exception() = context.AllErrors  

For Each ex As Exception In errs  
Response.Write("<p>" & Server.HtmlEncode(ex.ToString()) & "</p>")  
Next  

' Clear the exceptions so ASP.NET won't handle them.  
context.ClearError()  
End Sub  

備註

這個屬性是HttpContext類別的靜態屬性。This property is a static property of the HttpContext class. 屬性會儲存套用HttpContext至目前要求的實例。The property stores the HttpContext instance that applies to the current request. 這個實例的屬性是HttpContext類別的非靜態屬性。The properties of this instance are the non-static properties of the HttpContext class.

您也可以使用Page.Context屬性來HttpContext存取目前 HTTP 要求的物件。You can also use the Page.Context property to access the HttpContext object for the current HTTP request.
