声明中缺少部分现代

Question

当我尝试运行我的程序时，我如何纠正我得到的错误，我在网上找到了这个程序，它似乎是用 Visual c# 2005 编译的，我使用的是 Visual c# 2010 我在编译之前遇到了这两个错误

“RecursiveSearchCS.Form1.components”和“RecursiveSearchCS.Form1.components”之间的错误 2 歧义 'RecursiveSearchCS.Form1.components' C:\Users\jacr\AppData\Local\Temporary 项目\WindowsFormsApplication1\Form1.cs 46 21 WindowsFormsApplication1

错误 1 ​​以下方法之间的调用不明确或 属性：'RecursiveSearchCS.Form1.InitializeComponent()' 和 'RecursiveSearchCS.Form1.InitializeComponent()' C:\Users\jacr\AppData\Local\Temporary 项目\WindowsFormsApplication1\Form1.cs

32 13 WindowsFormsApplication1

当我尝试编译它时出现错误，我得到了这个

错误 1 ​​类型声明中缺少部分修饰符 '递归搜索CS.Form1';这种类型的另一个部分声明 存在 C:\Users\jacr\AppData\Local\Temporary 项目\WindowsFormsApplication1t\Form1.cs 14 18 WindowsFormsApplication1t

我到底应该做什么？我的程序在目录中搜索文件文本文件，但似乎我得到了这个错误......这是form1.cs上的代码

Answer 1

你给出的代码实际上编译得很好。

但是，查看错误，您似乎有两个副本：

C:\Users\jacr\AppData\Local\Temporary Projects\WindowsFormsApplication1\Form1.cs

C:\Users\jacr\AppData\Local\Temporary Projects\WindowsFormsApplication1t\Form1.cs

注意第二个目录名称末尾的“t”。

摆脱其中一个副本，应该没问题。 （您应该可以在 Visual Studio 中将其删除 - 我怀疑您可以同时看到 Form1.cs 文件...）

Answer 2

使用 partial 关键字扩展您的 class 声明：

public partial class Form1 : System.Windows.Forms.Form

Answer 3

试试partial关键字like;

public partial class Form1 : System.Windows.Forms.Form

编辑：看起来你有这个项目的两个副本；

C:\Users\jacr\AppData\Local\Temporary 项目\WindowsFormsApplication1\Form1.cs

和

C:\Users\jacr\AppData\Local\Temporary 项目\WindowsFormsApplication1t\Form1.cs

只需摆脱其中一个项目，因为您在同一个问题中询问它们。大概是这个原因吧。

Answer 4

正如大多数人已经告诉你的那样，你需要在你的类声明中使用partial-keyword。

public partial class Form1 : System.Windows.Forms.Form

当您使用 Windows 窗体时，Visal Studio 会将您的窗体拆分为多个文件（MyForm.cs 用于您的代码，MyForm.Designer.cs 用于您的 UI 元素的自动生成代码，有时还有一个与之配套的资源文件）。由于该类被拆分为多个文件，因此需要partial-关键字来告诉编译器在最终确定该类之前继续查找更多文件。

更多关于partial-关键字的信息可以在这里找到：http://msdn.microsoft.com/en-us/library/wa80x488%28v=vs.80%29.aspx
