我创建了一个组件来为我们的项目做一些本地化工作.我遇到的问题是,输出到InitializeComponent的代码输出太晚了.
例
this.components = new System.ComponentModel.Container();
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(ucHome));
this.localizationResourceManager1 = new Compass0.Localization.LocalizationResourceManager(this.components);
//Other designer code to create controls (this is all in the first block of code in InitializeComponent
Compass0.Localization.XMLResourceManager.Create(typeof(ucViewHome), ref resources); //created by my code serializier
//
// btnLogin
//
等
但是设计师所发生的是
this.components = new System.ComponentModel.Container();
System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(ucHome));
this.btnLogin = new ComponentFactory.Krypton.Toolkit.KryptonButton();
this.localizationResourceManager1 = new Compass0.Localization.LocalizationResourceManager(this.components);
//Other designer code to create controls (this is all in the first block of code in InitializeComponent
//
// btnLogin
//
this. btnLogin.Name = "btnLogin";
this. btnLogin.Text = resources.GetString("btnLogin.Text");
Compass0.Localization.XMLResourceManager.Create(typeof(ucViewHome), ref resources); //created by my code serializier
在资源初始化之后,我基本上需要强迫设计人员将代码放在第三行.有没有办法可以直接做到这一点？我的代码生成类如下.
public override object Deserialize( IDesignerSerializationManager manager, object codeDomObject )
{
CodeDomSerializer baseSerializer = ( CodeDomSerializer )manager.GetSerializer( typeof( LocalizationResourceManager ).BaseType, typeof( CodeDomSerializer ) );
return baseSerializer.Deserialize( manager, codeDomObject );
}
public override object Serialize( IDesignerSerializationManager manager, object value )
{
CodeDomSerializer baseSerializer = ( CodeDomSerializer )manager.GetSerializer( typeof( LocalizationResourceManager ).
BaseType, typeof( CodeDomSerializer ) );
object codeObject = baseSerializer.Serialize( manager, value );
if ( codeObject is CodeStatementCollection )
{
CodeStatementCollection statements = ( CodeStatementCollection )codeObject;
CodeTypeDeclaration classTypeDeclaration = ( CodeTypeDeclaration )manager.GetService(typeof( CodeTypeDeclaration ) );
CodeExpression typeofExpression = new CodeTypeOfExpression( classTypeDeclaration.Name );
CodeDirectionExpression resourceRef = new CodeDirectionExpression( FieldDirection.Ref, new CodeVariableReferenceExpression( "resources" ) );
CodeExpression ResourceManagerAssignment = new CodeMethodInvokeExpression(
new CodeTypeReferenceExpression( typeof(XMLResourceManager).ToString() ),
"Create", new CodeExpression[] { typeofExpression, resourceRef } );
statements.Insert( 0, new CodeExpressionStatement( ResourceManagerAssignment ) );
}
return codeObject;
}
解决方法:
我知道这真的很晚,但是对于任何偶然发现这个问题的人来说…
我在做完全相同的事情,要解决此问题,我只是通过创建一个从ComponentDesigner继承的类并使用Initialize方法来确保首先创建/序列化了本地化控件,该方法获取控件列表,删除自身并重新添加自身在列表的顶部.然后,将Designer属性添加到我的自定义组件中.
它在VB中,如果有人需要将其翻译为C#,请告诉我…
