Enterprise Library Additions: String Resource Generator

在Enterprise Library v1.0的Application Blocks中大量采用SR.strings作为字符串资源文件，记录应用程序中需要的输出信息。通过String Resource Generator处理后，该文件自动产生同名的.CS和.RESX文件。其中.CS文件是一个用来访问这些字符串资源的类，包括格式化参数的特性，如.NET 中{}格式相同，具体可以查阅String.Format帮助。
1. String Resource Generator简介
Version：1.2.5
作者：Martin, his blog: http://wah.onterra.net/blog/
Download: http://projectdistributor.readify.net/Projects/Project.aspx?projectId=2
安装：下载上诉MSI文件安装即可，通过VS.NET在现有的.RESX或SR.strings文件设置Custom tool属性为：StringResourceTool或SRCodeGen。
蝈蝈俊.net对上述工具也有简单介绍。
2. String Resource Generator v1.2.5新支持如下特性：
- 支持VB.NET（当然有C#）
- 支持改变类的名称，通过使用不同的.strings文件名
- 支持定制namespace，通过在solution explorer中设置custom tool namespace属性
- 支持多个.strings文件，如SR.strings, SR.strings-de, SR.strings-cn，要求后缀中不允许有. （dot）
- 当然还有好多其他功能，具体可以查询上述链接
3. SR.strings文件编辑
特殊字符说明：
#或; 注释字符串
#! 指定特殊选项
如#! accessor_class_accessibility = public 定义SR类为public，而不是缺省的internal。
#! culture_info = <YourCodeHere> 定义特定的culture，而不是缺省的Culture属性。
#! generate_class = false 设置不自动生成class，如下所示：
#! generate_class = false
[strings.de]
ResName = German blah
简单的方法是照着Enterprise Library中SR.strings文件编辑就可以了。如下是节选Security Application Block Quick Start中SR.strings文件：
#
# Options description:
#
# Options are specified as lines starting with "#!"
# To use an option below delete the first # in the corresponding line
# To define the SR class public instead of internal (default):
##! accessor_class_accessibility = public
# To use a code fragment as the culture instead of the Culture property (default):
##! culture_info = <YourCodeHere>
# for example, #! culture_info = MyResources.CommonCultureInfo
# where CommonCultureInfo is a static member of a class MyResources
#! accessor_class_accessibility = public
[strings]
#Messages used by database management scenarios
CreateUserTitleMessage = Create a new user
UserCreatedMessage(username) = User {0} created.
DeleteUserMessage(username) = User {0} deleted.
AddUserRoleMessage(username, role) = Role {1} added for user {0}.
DeleteUserRoleMessage(username, role) = Role {1} deleted for user {0}.
AddUserRoleErrorMessage = Please select a user name and select or enter a role.
DeleteUserRoleErrorMessage = Please select a user name and a role.
DeleteUserErrorMessage = Please select a user name.
ErrorMessage = Error
节选的SR.cs文件（并不是上述SR.strings对应的SR.cs类文件）：
public class SR
{
public static System.Globalization.CultureInfo Culture
{
get
{
return Keys.Culture;
}
set
{
Keys.Culture = value;
}
}
public static string AddUserRoleErrorMessage
{
get
{
return Keys.GetString(Keys.AddUserRoleErrorMessage);
}
}
public static string AuthenticateTitleMessage
{
get
{
return Keys.GetString(Keys.AuthenticateTitleMessage);
}
}
}
