Error cs1003 синтаксическая ошибка требуется

I am recreating Flappy bird as my first project in unity (version 2021.3.6f1). I’m using Visual Studio to compile the C# script.

I get error cs1003 ‘,’ expected on (8,42)

My Code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
    public Rigidbody2D rb;
    public FlightForce = new Vector2(0f, 10f);
    // Update is called once per frame
    void Update()
    {
    
        if (Input.GetKeyDown("space"))
        {
            rb.AddForce(FlightForce, ForceMode2D.Force);
        }
    }
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class PlayerMovement : MonoBehaviour
{
    public Rigidbody2D rb;
    public FlightForce = new Vector2(0f, 10f); // <--- you didn't provide the type here
    // Update is called once per frame
    void Update()
    {
    
        if (Input.GetKeyDown("space"))
        {
            rb.AddForce(FlightForce, ForceMode2D.Force);
        }
    }
}

Ok, so I’ve been trying to pass multiple models to a View using a Tuple and it’s worked like a charm so far. Problem comes when I try this

@model Tuple<Smart_WEB.Models.Room, List<IGrouping<string, Smart_WEB.Models.Song>>, List<IGrouping<string, Smart_WEB.Models.Video>>>

The error

Description: an error occurred during the compilation of a resource required to service this request. Please review the following specific error details and modify your source code appropriately.

Compiler Error Message: CS1003: Syntax error, ‘>’ expected

Source Error:


Line 29:

Line 30:

Line 31: public class _Page_Views_Home_Index_cshtml : System.Web.Mvc.WebViewPage<Tuple<Smart_WEB.Models.Room {
Line 32:

Line 33: #line hidden

And if I were to put something like:

@model Tuple<Smart_WEB.Models.Room, List<IGrouping<string, Smart_WEB.Models.Video>>>

Or

@model Tuple<Smart_WEB.Models.Room, List<IGrouping<string, Smart_WEB.Models.Song>>>

and the respective server side code it works perfectly.

Thanks in advance to anyone who can help me; I’m about to give up on this problem.

As you are basically passing multiple models in your view and MVC is designed to pass one type to one view, I strongly advise you to create a single model that wraps all your entities:

public class ViewModel
{
    public Smart_WEB.Models.Room Room { get; set; }
    public List<IGrouping<string, Smart_WEB.Models.Song>> Songs { get; set; }
    List<IGrouping<string, Smart_WEB.Models.Video>> Videos { get; set; }
}

Then you can set it as model in your view:

@model ViewModel

This is a working C#6 test code. It compiles on VS2015

namespace testcode
{
    class Program
    {
        static void Main(string[] args)
        {
            string x = null ;
            string y = x?.Substring(0, 2);
            return;
        }       
    }
}

The

cproj

has toolsversion

14.0


<Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

This is how I’m trying to compile it with

MSBUILD

via the

Visual Studio SDK

//References Microsoft.Build and Microsoft.Build.Framework
namespace MSBuildTest
{
    class Program
    {
        static void Main(string[] args)
        {
            var pc = new Microsoft.Build.Evaluation.ProjectCollection(Microsoft.Build.Evaluation.ToolsetDefinitionLocations.Registry);
            pc.DefaultToolsVersion = "14.0";
            pc.RegisterLogger(new Microsoft.Build.Logging.ConsoleLogger(Microsoft.Build.Framework.LoggerVerbosity.Detailed));
            var pr = pc.LoadProject(@"C:pathtotestcode.cproj");
            pr.Build();
        }
    }
}

This is the error message

Program.cs(8,26): error CS1525: Invalid expression term '.'
Program.cs(8,27): error CS1003: Syntax error, ':' expected
    0 Warning(s)
    2 Error(s)

I guess it’s using the wrong MSBUILD executable, but I found no way to force the MSBUILD bin path.

To Resolve this issue, Try below setting:

For anyone else that gets this error, don’t use the msbuild located at:
C:WindowsMicrosoft.NETFramework64v4.0.30319

Instead use the msbuild at:
C:Program Files (x86)MSBuild14.0Bin

You are referencing the older version of the

Microsoft.Build.*

libraries, make sure you are pointing at the right ones. If you use old ones you will be trying to build with C# v5 which doesn’t understand the null propogation operators.

For example, on my build machine they are:

C:Program Files (x86)MSBuild14.0BinMicrosoft.Build.dll

and

C:Program Files (x86)MSBuild14.0BinMicrosoft.Build.Framework.dll

Looks like you are using VB syntax in a page set up for C#. You need to decide which language you want to use.
