member this.ParseControl : string -> System.Web.UI.Control

Public Function ParseControl (content As String) As Control

參數

傳回

解析 Control過的 .

以下程式碼範例示範如何使用此方法建立Button網頁伺服器控制，並將結果ParseControl加入名為 ControlCollection的 Web 伺服器控制集合PlaceHoldermyPlaceholder中。

備註

這個 content 參數包含使用者控制項，就像你在 .ascx 檔案中看到的那樣。 此字串無法包含任何程式碼，因為該 ParseControl 方法不會進行編譯。

• LoadControl

public:
 System::Web::UI::Control ^ ParseControl(System::String ^ content, bool ignoreParserFilter);

public System.Web.UI.Control ParseControl(string content, bool ignoreParserFilter);

member this.ParseControl : string * bool -> System.Web.UI.Control

Public Function ParseControl (content As String, ignoreParserFilter As Boolean) As Control

參數

傳回

解析控制。

備註

該 content 參數包含使用者控制項（.ascx 檔案的內容）。 此字串無法包含任何程式碼，因為該 ParseControl 方法不會進行編譯。

參數 ignoreParserFilter 允許忽略該 PageParserFilter 類別。 PageParserFilter 類別由 ASP.NET 解析器用來判斷某個項目在解析時是否允許進入頁面。
