CodeSmith实用技巧(二):使用FileNameEditor
FileNameEditor类给我们提供了在CodeSmith属性面板中弹出打开或保存文件对话框的方式,在使用时,首先在模版中得添加对程序集CodeSmith.CustomProperties的引用。然后就可以在模版中定义一个属性来使用FileNameEditor:
1<script runat="template">
2
3private string _userFileName = @"c:\temp\test.txt";
4
5
6
7[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
8
9Category("Custom"), Description("User selected file.")]
10
11
12
13public string UserFileName
14
15{
16
17 get {return _userFileName;}
18
19 set {_userFileName= value;}
20
21}
22
23</script>
24
25
2
3private string _userFileName = @"c:\temp\test.txt";
4
5
6
7[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
8
9Category("Custom"), Description("User selected file.")]
10
11
12
13public string UserFileName
14
15{
16
17 get {return _userFileName;}
18
19 set {_userFileName= value;}
20
21}
22
23</script>
24
25
当我们执行该模版时,在属性面板中同样显示为一个按钮:
单击该按钮,弹出一个保存文件的对话框:
我们也可以通过FileDialogAttribute来自定义弹出的对话框,修改模版为:
1private string _openFileName = @"c:\temp\test.txt";
2
3
4[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
5
6FileDialogAttribute(FileDialogType.Open, Title="Select Input File"),
7
8Category("Custom"), Description("User selected file.")]
9
10
11
12public string OpenFileName
13
14{
15
16 get {return _openFileName;}
17
18 set {_openFileName= value;}
19
20}
21
22
2
3
4[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
5
6FileDialogAttribute(FileDialogType.Open, Title="Select Input File"),
7
8Category("Custom"), Description("User selected file.")]
9
10
11
12public string OpenFileName
13
14{
15
16 get {return _openFileName;}
17
18 set {_openFileName= value;}
19
20}

弹出的对话框如下所示:
当我们想用一个文件夹的名称来代替文件时,可以使用FolderNameEditor类。
1<%@ Assembly Name="System.Design" %>
2<script runat="template">
3private string _outputDirectory = @"c:\temp";
4[Editor(typeof(System.Windows.Forms.Design.FolderNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
5Category("Custom"), Description("Output directory.")]
6public string OutputDirectory
7{
8 get {return _outputDirectory;}
9 set {_outputDirectory= value;}
10}
11</script>
12
13
2<script runat="template">
3private string _outputDirectory = @"c:\temp";
4[Editor(typeof(System.Windows.Forms.Design.FolderNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
5Category("Custom"), Description("Output directory.")]
6public string OutputDirectory
7{
8 get {return _outputDirectory;}
9 set {_outputDirectory= value;}
10}
11</script>
