c# - WPF 设计器问题：XDG0008 名称“NumericTextBoxConvertor”在命名空间“clr-namespace:PulserTester.Convertors”中不存在

问题描述

我有一个错误，让我看不到我的设计师.. 但我在构建时没有错误，我的程序运行良好，没有问题

我试图：

清理和重建
更新 Visual Studio
修复 Visual Studio
重启我的电脑

没有任何帮助。我不知道我还能做些什么来解决它。

我必须尝试在这里查看，即使在重新启动 Visual Studio 后也没有为我工作，重新构建了解决方案

名称 <...> 不存在于命名空间 clr-namespace <...>

这是我的错误：

这是 Xaml 文件：

这是我的转换器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Data;

namespace PulserTester.Convertors
{
    public class NumericTextBoxConvertor : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            return value.ToString();
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            string val = value.ToString();

            long ret = long.TryParse(new string(val.Where(char.IsDigit).ToArray()), out long result) ? result : 0;
            if (ret > int.MaxValue)
            {
                ret = int.MaxValue;
            }
            return ret;
        }
    }
}
