在项目中经常需要实现多语言其中包括webpart的属性也需要。那么如何实现呢？
首先需要资源文件，利用资源文件实现语言的翻译，如下图：
创建好资源后，下面我们来实现webpart属性的多语言。方法代码如下：
1: using System;
2: using System.Collections.Generic;
3: using System.Text;
4: using System.Globalization;
5: using System.Web;
6: using System.Web.UI.WebControls.WebParts;
7: using System.ComponentModel;
8: //****************************************************************
9: //编制人：XX
10: //编制作用：本地化WebPart的Category、WebDisplayName 和 WebDescription 属性
11: //编制时间：2013-05-07
12: //编制单位：XX
13: //****************************************************************
14: namespace TCL.EP.SPCommon
15: {
16: #region//WebPart类别本地化
17: public sealed class LocalizedCategoryAttribute : CategoryAttribute
18: {
19: public LocalizedCategoryAttribute(string category)
20: : base(category)
21: { }
22:
23: // Override this method to return values from the webpart's resource file.
24: protected override string GetLocalizedString(string value)
25: {
26: return LocalizedUtility.GetLocalizedString(value, CultureInfo.CurrentUICulture.LCID);
27: }
28: }
29: #endregion
30:
31: #region//WebPart显示名称本地化
32: public sealed class LocalizedWebDisplayNameAttribute : WebDisplayNameAttribute
33: {
34: bool m_isLocalized;
35:
36: public LocalizedWebDisplayNameAttribute(string displayName)
37: : base(displayName)
38: { }
39:
40: // Override this property to return values from the webpart's resource file.
41: public override string DisplayName
42: {
43: get
44: {
45: if (!m_isLocalized)
46: {
47: this.DisplayNameValue = LocalizedUtility.GetLocalizedString(base.DisplayName, CultureInfo.CurrentUICulture.LCID);
48: m_isLocalized = true;
49: }
50: return base.DisplayName;
51: }
52: }
53: }
54: #endregion
55:
56: #region//WebPart描述本地化
57: public sealed class LocalizedWebDescriptionAttribute : WebDescriptionAttribute
58: {
59: bool m_isLocalized;
60:
61: public LocalizedWebDescriptionAttribute(string description)
62: : base(description)
63: { }
64:
65: // Override this property to return values from the webpart's resource file.
66: public override string Description
67: {
68: get
69: {
70: if (!m_isLocalized)
71: {
72: this.DescriptionValue = LocalizedUtility.GetLocalizedString(base.Description, CultureInfo.CurrentUICulture.LCID);
73: m_isLocalized = true;
74: }
75: return base.Description;
76: }
77: }
78: }
79: #endregion
80: }
调用例子如下：
1: /// <summary>
2: /// 图片打开的URL
3: /// </summary>
4: [WebBrowsable(true)]
5: [LocalizedWebDisplayName("TCL.WebPartAttribute.PhotoImageUrl")]
6: [LocalizedWebDescription("TCL.WebPartAttribute.PhotoImageUrl")]
7: [Personalizable(PersonalizationScope.Shared)]
8: [LocalizedCategory("TCL.WebPartAttribute.SelfName")]
9: public string PhotoImageUrl { get; set; }
