大家好，小弟程式新手，看了網路上部落格學習"http://deepgreat02.blogspot.com/2016/03/20160302.html"
目前照著範例嘗試，卻出現texbox問題，一直找不到哪裡錯，所以想請教各位先進。
嚴重性程式碼說明專案檔案行隱藏項目狀態

你檢查一下程式碼，通常public partial class WebForm1 : System.Web.UI.Page外面會有namespace的，你檢查一下到底應該是什麼，我猜是「WaterWebApplication」。

最佳解答

還是回答好了：

點選方案總管中WebForm1.aspx左側的三角形，你會看到兩個檔案
打開WebFrom1.aspx.designer.cs，看看他用的namespace是什麼
你程式public partial class WebForm1 : System.Web.UI.Page外面要用這個namespace包起來

因為你頁面上用的component是定義在這裡，如果namespace不一致的話，當然找不到。其實你查一下：
https://docs.microsoft.com/zh-tw/dotnet/csharp/language-reference/compiler-messages/cs0103
就可能會有線索。
