接口转换 数据库列表的内容 显示在datagrid

public class AddressConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            string result = string.Empty;

            if (value != null)
            {
                string[] CustomCode = value.ToString().Split(',');

                for (int i = 0; i < CustomCode.Count(); i++)
                {
                    var tempCustom = CodeListHelper.AllAddressList.Where(c => c.SelectValue == CustomCode[i]).FirstOrDefault();

                    if (i == 0)
                    {
                        if (tempCustom == null)
                        {
                            result = CustomCode[i];
                        }
                        else
                        {
                            result = tempCustom.DisplayValue;
                        }
                    }
                    else
                    {
                        if (tempCustom == null)
                        {
                            result += "," + CustomCode[i];
                        }
                        else
                        {
                            result += "," + tempCustom.DisplayValue;
                        }
                    }
                }

                return result;

            }

            return result;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

上面是转换活的例子,下面是转换死的例子

 public class CarTypeConverter : IValueConverter
    {
        public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
        {
            if (value != null)
            {
                var tempCustom = CodeListHelper.DispatchTypeList.Where(c => c.SelectValue == value.ToString()).FirstOrDefault();

                if (tempCustom != null)
                {
                    return tempCustom.DisplayValue;
                }
            }

            return value;
        }

        public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }

说这个意思。
