c# - WPF 设计器问题 : XDG0008 The name "NumericTextBoxConvertor" does not exist in the namespace "clr-namespace:PulserTester.Convertors"

Question

我有一个错误，不允许我看到我的设计师..但我在构建时没有错误，我的程序运行正常，没有问题

我尝试过:

• 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。

我必须尝试在此处查看，即使在重新启动 visual studio、重新构建解决方案后也没有为我工作

the name <...> does not exist in the namespace 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;
        }
    }
}

Answer 1

我只想重申一个解决方案 Bradley Uffner提埋in the comments above .

1. 关闭 Visual Studio

2. 删除隐藏的.vs文件夹

3. 打开 Visual Studio 并重建您的项目

请记住，这是一个非常普遍的错误，有多种原因和解决方案，因此这可能对您不起作用，但绝对值得一试，因为我知道它在过去曾多次对我有用。
