Cannot convert from 'Spectre.Console.Table' to 'string'
The following code returns the error:
using Spectre.Console;
namespace NewProject.Services;
public class ContextService : IContextService
{
private readonly IRootService _rootService;
public ContextService(IRootService rootService)
{
_rootService = rootService ?? throw new ArgumentNullException(nameof(rootService));
}
public void List()
{
var root = _rootService.GetPath();
DirectoryInfo info = new DirectoryInfo(root);
var directories = info.EnumerateDirectories();
var table = new Table();
table.Border = TableBorder.SimpleHeavy;
table.AddColumn("Context");
table.AddColumn("Path");
foreach (var item in directories)
{
table.AddRow(item.Name, item.FullName);
}
AnsiConsole.Write(table); // Here is C:\Repos\NewProject\Services\ContextService.cs(36,27)
}
}
The build output:
C:\Repos\NewProject\Services\ContextService.cs(36,27): error CS1503: Argument 1: cannot convert from 'Spectre.Console.Table' to 'string' [C:\Repos\NewProject\NewProject.csproj]
The build failed. Fix the build errors and run again.
Could anyone help me?
What version of Spectre.Console are you using? .NET 6?
Thank you for so fast reply, it's awesome! Yes: .NET 6.0.203, Spectre.Console 0.41.0.
One of the versions since 0.41.0 we switched around some syntax to make things consistent in their behavior. Back then Write
only took a string and you'd need to use Render
for any of the IRenderable
elements.
I'd recommend updating to a new version as we've done a ton of improvements in the past year.
Great idea, but I couldn't use other examples from documentation with the recent versions... All right, let's forget about it. Thank you for your support.
What examples didn't work? If that's the case then we want to address that.
Need to figure out what part of the documentation is wrong with the latest version. @gjaryczewski Any help would be appreciated here.
:-) All right, I will repeat the exercise and find something useful during the weekend.
All right, so the Program.cs looks like this:
using Microsoft.Extensions.DependencyInjection;
using Spectre.Console;
using Spectre.Console.Cli;
public static class Program
{
public static int Main(string[] args)
{
var app = new CommandApp();
app.Configure(config =>
{
config.PropagateExceptions();
});
try
{
return app.Run(args);
}
catch (Exception ex)
{
AnsiConsole.WriteException(ex, ExceptionFormats.ShortenEverything);
return -99;
}
}
}
The .csproj file looks like this:
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>net6.0</TargetFramework>
<RootNamespace>test_spectre</RootNamespace>
<ImplicitUsings>enable</ImplicitUsings>
<Nullable>enable</Nullable>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="Microsoft.Extensions.DependencyInjection" Version="6.0.0" />
<PackageReference Include="Spectre.Console" Version="0.45.0" />
</ItemGroup>
</Project>
The output of the build process contains: C:\Users\gjary\Repos\test-spectre\Program.cs(3,23): error CS0234: The type or namespace name 'Cli' does not exist in the namespace 'Spectre.Console' (are you missing an assembly reference? [C:\Users\gjary\Repos\test-spectre\test-spectre.csproj]
.
According to the tutorial documentation, CommandApp is the entry point for a Spectre.Console.Cli command line application, this is also repeated in API Reference.
The previous code works with 0.44. Does not work with 0.45.
We split the Spectre.Console.Cli
stuff into its own NuGet package for 0.45: https://www.nuget.org/packages/spectre.console.cli
This is a good catch though I'll update the docs tonight to include a reference to the new package
