小编Nim*_*shi的帖子

我安装了Visual Studio 2013 Preview.现在,我想创建一个与MVC项目模板帮助一个asp.net web应用程序,但我得到这个异常:

例外HResult:0*80070002

我用Owin Startup类开发了一个应用程序.当我运行OwinHost.exe时,它显示No Assembly found containing OwinStartupAttribute.

但我在我的启动类中定义了程序集:

[assembly: OwinStartup(typeof(OwinDemo.BrandStartup))]

我还在Web.Config文件中定义了appSettings:

<appSettings>
<add key="owin:AppStartup" value="OwinDemo.Startup, OwinDemo"/>

我正在开发一个ASP.NET应用程序.我有一个名为ExcelApp的Excel 2013文件,我也在我的项目中添加了.我无法访问该文件.

这是我的DAL类:

public string ExcelConnection = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Nimit\ExcelApplication.xlsx;Extended Properties='Excel 12.0 Xml';HDR=YES"; 
    OleDbDataAdapter DbAdap;
    DataTable dt;

    public DataTable Get_ExcelSheet()
    {
        OleDbConnection DbCon = new OleDbConnection(ExcelConnection);

        DbAdap = new OleDbDataAdapter("SELECT * FROM [Sheet1$]",DbCon);
        dt = new DataTable();
        DbAdap.Fill(dt);
        return dt;
    }

我的cs文件代码:

public partial class WebForm1 : System.Web.UI.Page
{
    DAL obj = new DAL();
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack == true)
        {
            Get_Data();
        }
    }

    void Get_Data()
    {
        GridView1.DataSource = obj.Get_ExcelSheet();
        GridView1.DataBind();
    }
}

我的调试器在执行此行时显示错误:

DbAdap.Fill(dt);

例外是:

我正在按照以下链接中显示的教程:

为ASP.NET MVC应用程序创建实体框架数据模型

但在运行应用程序时,会出现以下异常:

System.IO.FileNotFoundException:无法加载文件或程序集"Vag_Infotech"或其依赖项之一.该系统找不到指定的文件.

我的web.config文件如下:

<connectionStrings>
  <add name="CollegeDbContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=VInfotech;Integrated Security=SSPI" providerName="System.Data.SqlClient"/>
</connectionStrings>

<contexts>
  <context type="Vag_Infotech.DAL.CollegeDbContext, Vag_Infotech">
    <databaseInitializer type="Vag_Infotech.DAL.CollegeDatabaseInitializer, Vag_Infotech"></databaseInitializer>
  </context>
</contexts>

CollegeDbContext课程:

namespace Vag_Infotech.DAL
{
public class CollegeDbContext : DbContext 
{
    public CollegeDbContext()
        : base("CollegeDbContext")
    {

    }

    public DbSet<Student> Students { get; set; }
    public DbSet<Course> Courses { get; set; }
    public DbSet<Enrollment> Enrollments { get; set; }
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
    }
}

}

StudentController.cs类中有例外:

我遵循了本教程,但是我在新的存储库中创建新分支时遇到了麻烦.这是我得到的错误:

我究竟做错了什么？

我有一个 C# 代码来执行批处理文件。我想在命令提示符中显示bat文件中的信息。这是我新编辑的 C# 代码：

namespace CheckTime
{
class Program
{
    static void Main(string[] args)
    {
        Program Obj = new Program();

        int greetingId;
        int hourNow = System.DateTime.Now.Hour;

        if (hourNow < 12)
            greetingId = 0;
        else if (hourNow < 18)
            greetingId = 1;
        else
            greetingId = 2;
        System.Environment.ExitCode = greetingId;
        Obj.StartBatchFile(greetingId);


    }

   void StartBatchFile(int Gretting)
    {
        var p = new Process();
        p.StartInfo.FileName = "cmd.exe";
        p.StartInfo.Arguments = string.Format(@"/C D:\Nimit Joshi\Visual Studio 2013\CheckTime\CheckTime\Demo1.bat {0}", Gretting);            
        p.OutputDataReceived += ConsumeData;


        try
        {
            p.Start();
            p.WaitForExit();
        } …

我在角6.起初，我已经成功地安装创建的项目在该项目中@progress/kendo-angular-dateinputs使用npm install，然后工程顺利建设。

运行ng-serve后出现如下错误：

node_modules/@progress/kendo-angular-dateinputs/dist/es2015/calendar/header.component.d.ts(2,37): error TS2307: Cannot find module '@progress/kendo-angular-l10n'.

node_modules/@progress/kendo-angular-dateinputs/dist/es2015/calendar/header.component.d.ts(3,29): error TS2307: Cannot find module '@progress/kendo-angular-intl'.

当我安装上述控件时，我的项目现在没有构建。以下错误即将到来：
