Question

我怎样才能纠正我在尝试运行程序时遇到的错误，我在网上找到了这个程序，它似乎是在visual c＃2005中编译的，我使用visual c＃2010 我在编译之前得到了这两个错误

错误2'RecursiveSearchCS.Form1.components'和。之间的歧义   'RecursiveSearchCS.Form1.components'C：\ Users \ jacr \ AppData \ Local \ Temporary   Projects \ WindowsFormsApplication1 \ Form1.cs 46 21 WindowsFormsApplication1

错误1以下方法或之间的调用不明确   properties：'RecursiveSearchCS.Form1.InitializeComponent（）'和   'RecursiveSearchCS.Form1.InitializeComponent（）'C：\ Users \ jacr \ AppData \ Local \ Temporary   项目\ WindowsFormsApplication1 \ Form1.cs中

32 13 WindowsFormsApplication1

当我尝试使用错误编译它时我得到了这个

错误1在声明类型时缺少部分修饰符 'RecursiveSearchCS.Form1';另一种这种类型的部分声明存在C：\ Users \ jacr \ AppData \ Local \ Temporary Projects \ WindowsFormsApplication1t \ Form1.cs 14 18 WindowsFormsApplication1t

我应该做什么？我的程序搜索目录中的文件文本文件，但似乎我收到此错误...这是form1.cs上的代码

Answer 1

使用class关键字扩展您的partial声明：

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

Answer 2

您提供的代码实际上编译得非常好。

然而，看看错误，你似乎有两份副本：

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

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

注意第二个目录名末尾的“t”。

摆脱其中一个副本，它应该没问题。（您应该能够在Visual Studio中删除它 - 我怀疑您可以看到两个Form1.cs文件...）

Answer 3

尝试使用partial关键字;

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

编辑：看起来你有两个这个项目的副本;

C：\用户\ jacr \应用程序数据\本地\临时项目\ WindowsFormsApplication1 \ Form1.cs中

和

C：\用户\ jacr \应用程序数据\本地\临时项目\ WindowsFormsApplication1t \ Form1.cs中

只是摆脱其中一个项目，因为你在同一个问题上问他们。可能这就是原因。

Answer 4

正如大多数人已经告诉过你的那样，你需要在你的班级声明中使用partial - 关键字。

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

当您使用Windows窗体时，Visal Studio会将您的表单拆分为多个文件（MyForm.cs用于您的代码，MyForm.Designer.cs用于自动生成的UI元素代码，有时还包含资源文件））。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完成此类之前继续查找更多文件。
