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
3
private string _userFileName = @"c:\temp\test.txt";
4
5
6
7
[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
8
9
Category("Custom"), Description("User selected file.")]
10
11
12
13
public string UserFileName
14
15
{
16
17
get {return _userFileName;}
18
19
set {_userFileName= value;}
20
21
}
22
23
</script>
24
25
<script runat="template">2

3
private string _userFileName = @"c:\temp\test.txt";4

5
6

7
[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),8

9
Category("Custom"), Description("User selected file.")]10

11
12

13
public string UserFileName14

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:
1
private string _openFileName = @"c:\temp\test.txt";
2
3
4
[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
5
6
FileDialogAttribute(FileDialogType.Open, Title="Select Input File"),
7
8
Category("Custom"), Description("User selected file.")]
9
10
11
12
public string OpenFileName
13
14
{
15
16
get {return _openFileName;}
17
18
set {_openFileName= value;}
19
20
}
21
22
private string _openFileName = @"c:\temp\test.txt";2

3

4
[Editor(typeof(FileNameEditor), typeof(System.Drawing.Design.UITypeEditor)),5

6
FileDialogAttribute(FileDialogType.Open, Title="Select Input File"),7

8
Category("Custom"), Description("User selected file.")]9

10
11

12
public string OpenFileName13

14
{15

16
get {return _openFileName;}17

18
set {_openFileName= value;}19

20
}21

22

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">
3
private string _outputDirectory = @"c:\temp";
4
[Editor(typeof(System.Windows.Forms.Design.FolderNameEditor), typeof(System.Drawing.Design.UITypeEditor)),
5
Category("Custom"), Description("Output directory.")]
6
public string OutputDirectory
7
{
8
get {return _outputDirectory;}
9
set {_outputDirectory= value;}
10
}
11
</script>
12
13
<%@ Assembly Name="System.Design" %>2
<script runat="template">3
private string _outputDirectory = @"c:\temp";4
[Editor(typeof(System.Windows.Forms.Design.FolderNameEditor), typeof(System.Drawing.Design.UITypeEditor)),5
Category("Custom"), Description("Output directory.")]6
public string OutputDirectory7
{8
get {return _outputDirectory;}9
set {_outputDirectory= value;}10
}11
</script>12
