我正在尝试为多种语言本地化WinForms应用。我正在尝试找到一种方法来设置我的表单标签/按钮文本属性以从设计器中的资源文件中读取(而不是必须维护一段以编程方式设置它们的代码)。
我发现我可以设置form.Localizable = true,但随后从表单旁边的文件中读取资源,但我的许多资源都是以多种形式共享的。
有没有办法在设计器中将标签的文本设置为存储在项目级resx文件中的值?

要回答这个问题,不。
但IMO,如果文本是静态的,不应该这样做。

我想我找到了办法做到这一点!
首先在Resources.resx中将Access Modifier设置为Public。
之后在设计器生成的代码(Form.Designer.cs)中,您可以将其写入适当的控件:
this.<control>.Text = Properties.Resources.<stringname>
例如:
this.footerLabel.Text = Properties.Resources.footerString;
ps.:我不知道这个解决方案有多道德,但它有效!

顺便说一句,这很容易实现,可以为您想要绑定到资源或任何其他类的任何类型的控件执行此操作。我这样做也适用于我的应用程序设置之类的静态类。
输入如下代码:
textBox2.DataBindings.Add("Text", source, "<className>.<PropertyName>");
没有给我一个“好感觉”,更别提拼写了
以下是上述标签的小样本,它提供了应用程序资源的下拉列表。
首先,控件包含一个名为 ResourceName 的新属性 魔术来自编辑器,这个在属性上方的注释中指定,并被称为 ResourceDropDownListPropertyEditor
[Editor(typeof(ResourceDropDownListPropertyEditor), typeof(System.Drawing.Design.UITypeEditor))]
标签类的代码:
/// <summary>
/// Label bound to resource
/// </summary>
/// <remarks>
/// The bitmap does not appear in the Toolbox for autogenerated controls and components.
/// https://docs.microsoft.com/en-us/dotnet/framework/winforms/controls/how-to-provide-a-toolbox-bitmap-for-a-control</remarks>
/// <seealso cref="System.Windows.Forms.Label" />
[ToolboxBitmap(typeof(Label))]
public partial class ResourceLabel : Label
{
/// <summary>
/// backing field for the resource key property
/// </summary>
private string mResourceName;
[Browsable(true)]
[DefaultValue("")]
[SettingsBindable(true)]
[Editor(typeof(ResourceDropDownListPropertyEditor), typeof(System.Drawing.Design.UITypeEditor))]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
[Description("Select the resource key that you would like to bind the text to.")]
public string ResourceName
{
get { return mResourceName; }
set
{
mResourceName = value;
if (!string.IsNullOrEmpty(mResourceName))
{
base.Text = Properties.Resources.ResourceManager.GetString(mResourceName);
}
}
}
/// <summary>
/// Designer helper method: https://msdn.microsoft.com/en-us/library/ms973818.aspx
/// </summary>
/// <returns><c>true</c> if XXXX, <c>false</c> otherwise.</returns>
private bool ShouldSerializeResourceName()
{
return !string.IsNullOrEmpty(ResourceName);
}
/// <summary>
/// Will be default text if no resource is available
/// </summary>
[Description("default text if no resource is assigned or key is available in the runtime language")]
public override string Text
{
get { return base.Text; }
set
{
// Set is done by resource name.
}
}
}
以下是用于下拉列表的类:
/// <summary>
/// used for editor definition on those properties that should be able
/// to select a resource
/// </summary>
/// <seealso cref="System.Drawing.Design.UITypeEditor" />
class ResourceDropDownListPropertyEditor : UITypeEditor
{
IWindowsFormsEditorService _service;
/// <summary>
/// Gets the editing style of the <see cref="EditValue"/> method.
/// </summary>
/// <param name="context">An ITypeDescriptorContext that can be used to gain additional context information.</param>
/// <returns>Returns the DropDown style, since this editor uses a drop down list.</returns>
public override UITypeEditorEditStyle GetEditStyle(ITypeDescriptorContext context)
{
// We're using a drop down style UITypeEditor.
return UITypeEditorEditStyle.DropDown;
}
/// <summary>
/// Displays a list of available values for the specified component than sets the value.
/// </summary>
/// <param name="context">An ITypeDescriptorContext that can be used to gain additional context information.</param>
/// <param name="provider">A service provider object through which editing services may be obtained.</param>
/// <param name="value">An instance of the value being edited.</param>
/// <returns>The new value of the object. If the value of the object hasn't changed, this method should return the same object it was passed.</returns>
public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value)
{
if (provider != null)
{
// This service is in charge of popping our ListBox.
_service = ((IWindowsFormsEditorService)provider.GetService(typeof(IWindowsFormsEditorService)));
if (_service != null)
{
var items = typeof(Properties.Resources).GetProperties()
.Where(p => p.PropertyType == typeof(string))
.Select(s => s.Name)
.OrderBy(o => o);
var list = new ListBox();
list.Click += ListBox_Click;
foreach (string item in items)
{
list.Items.Add(item);
}
if (value != null)
{
list.SelectedValue = value;
}
// Drop the list control.
_service.DropDownControl(list);
if (list.SelectedItem != null && list.SelectedIndices.Count == 1)
{
list.SelectedItem = list.SelectedItem.ToString();
value = list.SelectedItem.ToString();
}
list.Click -= ListBox_Click;
}
}
return value;
}
private void ListBox_Click(object sender, System.EventArgs e)
{
if (_service != null)
_service.CloseDropDown();
}
}
当您在表单上删除控件时,会创建资源名称,直到您重新编译并关闭/打开表单或在表单上删除新标签时才会看到更改。

我能想到的唯一方法是创建一个自定义控件来为资源名称添加属性。设置属性后,从项目资源文件中获取值并使用它设置text属性。您需要确保Text不会被序列化,或者它可能会覆盖ResourceName设置的值。
public class ResourceLabel
: Label
{
private string mResourceName;
public string ResourceName
{
get { return mResourceName; }
set
{
mResourceName = value;
if (!string.IsNullOrEmpty(mResourceName))
base.Text = Properties.Resources.ResourceManager.GetString(mResourceName);
}
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public override string Text
{
get { return base.Text; }
set
{
// Set is done by resource name.
}
}
}

我一直在看这个东西。
如果您拥有控件,即它是您自己的自定义控件,则可以使用CodeDOM
阅读this article以获得一些背景知识,并阅读download this example来了解它的完成方式。
在我们的应用中,我们需要使用数据库中的“ DisplayText”替换占位符。
因此,我们拥有"Order {Product}"
之类的Text属性,并且我们希望将其替换为GetDisplayText("Order {Product}
“)`。
为此,我添加了以下代码:
statements.OfType<CodeAssignStatement>()
.Where(s => s.Left is CodePropertyReferenceExpression && ((CodePropertyReferenceExpression)s.Left).PropertyName == "Text")
.ToList().ForEach(s =>
{
s.Right = new CodeMethodInvokeExpression(
new CodeMethodReferenceExpression(new CodeTypeReferenceExpression("Core.DisplayText"), "GetDisplayText"),
s.Right);
});
但是我仍在尝试它,但是我还没有创建一个可行的解决方案...但这可能会对您有所帮助。
