c# - 在 Visual Studio 中使用自定义应用程序根文件夹发布 c# 项目

问题描述

我需要一些帮助。我已经完成了我的应用程序的编码工作，但我在发布应用程序时遇到了一些挑战。我已经设法将数据库复制到输出目录但是，将图像目录添加到输出目录对我来说已经成为一个非常大的问题。图像目录包含可通过应用上传的自定义图像。我对 .csproj 做了一些更改，但徒劳无功。

.csproj

<Target Name="ContentsBeforeBuild" AfterTargets="BeforeBuild">
    <ItemGroup>
      <Content Include="images\*.*">
        <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </Content>
    </ItemGroup>
  </Target>

并且还使用了

<Target Name="ContentsBeforeBuild" AfterTargets="BeforeBuild">
    <ItemGroup>
      <Content Include="images\**">
        <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </Content>
    </ItemGroup>
  </Target>

这是检索图像并将其显示到我的应用程序的代码。它在发布应用程序之前工作正常，但在发布之后，它返回目录未找到异常。

 String paths = Application.StartupPath.Substring(0, (Application.StartupPath.Length - 10));

                    String imagePath = paths+"\\images\\"+col["itemPhoto"].ToString();

错误。发布后无法访问图片目录

图片未找到目录错误

他们有什么其他方式我可以编写代码以便从应用程序中获取图像吗？我需要一些帮助。

一个多星期试图发布我的应用程序..请帮助

.csproj

解决方案

我认为问题在于您尝试访问图像文件夹的方式。就像我在评论中所说的那样，在您部署应用程序后路径将不匹配（因为您正在执行子字符串）。

由于您正在复制图像文件夹，因此您不需要执行子字符串。

试试这个：

String imagePath = Application.StartupPath+"\\images\\"+col["itemPhoto"].ToString();

你能修改你的csproj文件吗？ 

<ItemGroup>
  <Content Include="images\alfa_romeo.jpg">
     <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </Content>    
</ItemGroup>

并删除您现有的

  <ItemGroup>
    <Content Include="images\**">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
  </ItemGroup>

这行：

在此处输入图像描述
