C# 比较字符串列表和布尔值列表

目前，我这样做是为了设置这么多布尔属性的可见性。我想要一个通用的方法来获取布尔属性列表和字符串列表，然后根据列表中是否存在特定字符串返回布尔列表

private void UpdateColumns(object c)
{
        if (c == null)
            return;

        var cols = ((IEnumerable)c).Cast<string>().ToList();            

        IsName = cols.Contains("Name") ? true : false;
        IsStatus = cols.Contains("Status") ? true : false;
        IsSize = cols.Contains("Size") ? true : false;
        IsHeight = cols.Contains("Height") ? true : false;
        IsWidth = cols.Contains("Width") ? true : false;
        IsImageType = cols.Contains("Image Type") ? true : false;
        IsFileName = cols.Contains("File Name") ? true : false;
        IsCreationDate = cols.Contains("Creation Date") ? true : false;
        IsEffectiveDate = cols.Contains("Effective Date") ? true : false;
        IsEndDate = cols.Contains("End Date") ? true : false;
        IsDescription = cols.Contains("Description") ? true : false;
}

不确定如何使用bool控制可见性。但带参数的转换器可能会有所帮助

public class ViewModel
    {
        public ViewModel()
        {
            Columns = new List<string>
            {
                "Width", "Height"
            };
        }
        public List<string> Columns { get; private set; }
    }

public class CustomizedConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            List<string> list = value as List<string>;
            string keyword = parameter as string;
            return list.Contains(keyword);
        }
        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

<StackPanel>
        <TextBox Text="Width" IsEnabled="{Binding Columns, Converter={StaticResource CustomizedConverter}, ConverterParameter='Width'}" />
        <TextBox Text="Height" IsEnabled="{Binding Columns, Converter={StaticResource CustomizedConverter}, ConverterParameter='Height'}" />
        <TextBox Text="None" IsEnabled="{Binding Columns, Converter={StaticResource CustomizedConverter}, ConverterParameter='None'}" />
    </StackPanel>

请先读这个。欢迎来到Stackoverflow。这不适合这里。到目前为止你有试过什么吗？先表现出你的努力，这样人们才能表现出他们的努力。请阅读并显示一些代码。还不清楚您试图实现什么以及您面临什么问题返回myStringList.ContainssampleString；对不起，我解释不清楚。实际上，我已经在视图模型中使用带有布尔属性的代理绑定绑定了datagrid每个列的可见性。在datagrid上下文菜单中，我绑定了打开列选择对话框的命令。在用户选择列之后，我得到所选列名称的字符串列表。因此，如果列表中存在特定的列名，我想设置布尔属性的值。请帮助我，因为我是mvvm的新手。Jason Li Thanx很多。这对我来说很有用，我已经定制了这个转换器来设置列的可见性

Yes thats works for me . Thanx a lot. I have created the converter to set the visibility of the columns



public class ColumnVisibilityConverter : IValueConverter
{
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
                {
                    List<string> list = value as List<string>;
                    string colName = parameter as string;
                    var visibility = list.Contains(colName) ? Visibility.Visible : Visibility.Collapsed;
                    return visibility;
                }
                public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
                {
                    throw new NotImplementedException();
                }
            }


and in xaml i have binded like this

<DataGridTextColumn Header="Name" MinWidth="200" Binding="{Binding Name}" CanUserResize="True"  Visibility="{Binding Data.Columns,Source={StaticResource proxy},Converter={StaticResource ColumnVisibilityConverter}, ConverterParameter='Name'}"/>
<DataGridTextColumn Header="Status" Binding="{Binding Status}" MinWidth="140" CanUserResize="True" Visibility="{Binding Data.Columns,Source={StaticResource proxy},Converter={StaticResource ColumnVisibilityConverter}, ConverterParameter='Status'}" />
<DataGridTextColumn Header="File Name" Binding="{Binding FileName}" MinWidth="150" CanUserResize="True" Visibility="{Binding Data.Columns,Source={StaticResource proxy},Converter={StaticResource ColumnVisibilityConverter}, ConverterParameter='File Name'}" />
<DataGridTextColumn Header="Size" Binding="{Binding ImgSize}" MinWidth="100" CanUserResize="True" Visibility="{Binding Data.Columns,Source={StaticResource proxy},Converter={StaticResource ColumnVisibilityConverter}, ConverterParameter='Size'}" />
<DataGridTextColumn Header="Height" Binding="{Binding Height}" MinWidth="100" CanUserResize="True" Visibility="{Binding Data.Columns,Source={StaticResource proxy},Converter={StaticResource ColumnVisibilityConverter}, ConverterParameter='Height'}" />
                    <DataGridTextColumn Header="Width" Binding="{Binding Width}" MinWidth="100" CanUserResize="True" Visibility="{Binding Data.Columns,Source={StaticResource proxy},Converter={StaticResource ColumnVisibilityConverter}, ConverterParameter='Width'}" />


and in view model i have updated the columns according to the selecting list

private void UpdateColumns(object c)
{
           if (c == null)
                return;

            var cols = ((IEnumerable)c).Cast<string>().ToList();

            Columns.Clear();
            Columns.AddRange(cols);
            RaisePropertyChanged(() => Columns);
}
