Linux下Mono编译C#项目报错：找不到ListCollectionView

Alright, let's tackle this issue you're facing with compiling your C# project using Mono on Linux. The error about missing ListCollectionView stems from common gaps in WPF-related assembly handling in Mono, and here are the actionable fixes to get your project compiling:

1. Explicitly reference required WPF assemblies #

ListCollectionView lives in the PresentationFramework.dll assembly, which isn't included by default in standard Mono compilations. You need to explicitly reference this (and supporting) assemblies when compiling.

When using mcs (Mono's C# compiler), run your compile command like this:

mcs -r:PresentationFramework.dll -r:WindowsBase.dll -r:System.dll SNAPoolLib.cs

• PresentationFramework.dll: Contains ListCollectionView and other WPF data binding types
• WindowsBase.dll: Required for CollectionViewSource and core WPF infrastructure
• System.dll: Covers basic system types (safe to specify even if auto-included by default)

2. Install Mono's WPF components #

If you still get assembly-not-found errors after adding references, you likely don't have the Mono WPF packages installed on your Linux system.

For Debian/Ubuntu-based systems:

sudo apt-get install mono-devel mono-wpf

For RPM-based systems (like Fedora):

sudo dnf install mono-devel mono-wpf

This ensures all WPF-related libraries are present on your machine.

3. Switch to a more portable interface (alternative approach) #

If you don't rely on ListCollectionView's specific features, consider using the ICollectionView interface instead. This makes your code more cross-platform compatible (works with .NET Framework, .NET Core, and Mono) and avoids tying to a concrete WPF implementation.

Modify your code like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Collections.ObjectModel;
using System.Windows.Data;

namespace SNAPoolLib
{
    public class ObservableList<T>: ObservableCollection<T>
    {
        ICollectionView _p_view;
        public ICollectionView _View
        {
            get
            {
                if (_p_view == null)
                {
                    // No casting needed - GetDefaultView returns ICollectionView directly
                    _p_view = CollectionViewSource.GetDefaultView(this);
                }
                return _p_view;
            }
        }

        public ObservableList() : base() { }
        public ObservableList(IEnumerable<T> items) : base(items) { }
    }
}

This change preserves all core collection view functionality (filtering, sorting, etc.) while improving portability.

4. Update to a recent Mono version #

Older Mono releases had incomplete WPF support. If you're running an outdated version, upgrade to the latest stable release (6.x or newer) to ensure better compatibility with WPF types.
