c# - 将此 C# 代码转换为经典 ASP/VBScript?

我知道这听起来倒退,但我必须将其从 C# 转换为经典 ASP。我不懂任何 VBScript,所以我需要帮助。

在我的 C# 代码中,它读取配置文件中的 appkeys,解析它们,并使用循环来执行一个过程。我不知道如何在 VBScript 中执行字典和 I/O 操作。有人可以帮忙吗?

这些是我想我必须作为常量变量存储在 .asp 文件中的键:

<add key="Output.Size" value="550" />
<add key="Output.Ext" value=".jpg" />
<add key="Output.Folder" value="thumbs" />
<add key="Suffix.LG" value="750" />
<add key="Suffix.TN" value="250" />
<add key="Suffix.TNL" value="175" />
<add key="Suffix.TNR" value="75" />
<add key="Supported" value=".jpeg,.jpg,.gif,.bmp,.tiff,.png" />

这是 C# 代码:

Generate generate = new Generate();
generate.Process(source, destination); //inputs will be relative URL paths

public class Generate
{
private const string OUTPUT_SIZE_KEY = "Output.Size";
private const string OUTPUT_EXT_KEY = "Output.Ext";
private const string SUFFIX_KEY = "Suffix.";
private const string SUPPORTED_KEY = "Supported";
private string[] supportedExt = null;

public Generate()
{
//GET ALL SUPPORTED FORMAT TYPES TO PREVENT PROCESSING ON UNSUPPORTED FILES
supportedExt = ConfigurationManager.AppSettings[SUPPORTED_KEY].ToLower().Split(',');
}

public void Process(string sourceDir, string destDir)
{
int thumbSize = Int32.Parse(ConfigurationManager.AppSettings[OUTPUT_SIZE_KEY]);
string thumbExt = ConfigurationManager.AppSettings[OUTPUT_EXT_KEY];

//COLLECT VALUES FOR RESIZING
Dictionary<string, int> resizeValues = new Dictionary<string, int>();
foreach (string item in ConfigurationManager.AppSettings.AllKeys)
{
if (item.StartsWith(SUFFIX_KEY))
{
resizeValues.Add(item.Substring(SUFFIX_KEY.Length), Int32.Parse(ConfigurationManager.AppSettings[item]));
}
}

//BEGIN GENERATING THUMBS
foreach (string item in Directory.GetFiles(sourceDir))
{
//VALIDATE IF FILE TYPE SUPPORTED
if (!supportedExt.Contains(Path.GetExtension(item.ToLower())))
continue;

string fileName = Path.GetFileNameWithoutExtension(item);
string outputFile = Path.Combine(destDir, fileName + thumbExt);

//RESIZE TO THUMB
Resize(item, outputFile, thumbSize); //DO NOT HAVE TO CONVERT "RESIZE"

//RESIZE TO DIFFERENT THUMBS
foreach (KeyValuePair<string, int> output in resizeValues)
{
string thumbSeq = Path.Combine(destDir, fileName + output.Key + thumbExt);
Resize(item, thumbSeq, output.Value); //DO NOT HAVE TO CONVERT "RESIZE"
}
}
}

更新:按照下面的建议,我转换为 VB 以便于翻译。看来我也得重新考虑一下了。这是我所在的位置,但出现错误:

<html>
<head>
<title></title>
</head>
<body>
<%

'DECLARE VARIABLES
Dim outputSize
Dim outputExt
Dim outputSuffix()
Dim supported
Dim source
Dim destination

'INITIALIZE VALUES
outputSize = 550
outputExt = ".jpg"
outputSuffix(0) = "LG.750"
outputSuffix(1) = "TN.250"
outputSuffix(2) = "TNL.175"
outputSuffix(3) = "TNR.75"
supported = ".jpeg,.jpg,.gif,.bmp,.tiff,.png"
source = "catalog/upload"
destination = "catalog"

'CALL FUNCTION TO RESIZE THUMBNAILS
Dim generate
generate = New ThumbGenerator
generate.Process source, destination

'PROCESS TO RESIZE
class ThumbGenerator
Dim supportedExt

Public Sub Process(sourceDir, destDir)
Dim thumbSize
Dim thumbExt
thumbSize = outputSize
thumbExt = outputExt
supportedExt = supported.ToLower().Split(",")

'COLLECT VALUES FOR RESIZING
Dim resizeValues
resizeValues = Dictionary(String, Integer)()
For Each item As String In outputSuffix
Dim temp
temp = item.Split(".")
resizeValues.Add(temp(0), temp(1))
Next

'BEGIN GENERATING THUMBS
For Each item As String In Directory.GetFiles(sourceDir)
'VALIDATE IF FILE TYPE SUPPORTED
If Not supportedExt.Contains(Path.GetExtension(item.ToLower())) Then
Continue For
End If

Dim fileName
Dim outputFile
fileName = Path.GetFileNameWithoutExtension(item)
outputFile = Path.Combine(destDir, fileName + thumbExt)

'RESIZE TO THUMB
'Resize(item, outputFile, thumbSize)

'RESIZE TO DIFFERENT THUMBS
For Each output As KeyValuePair(Of String, Integer) In resizeValues
Dim thumbSeq As String = Path.Combine(destDir, fileName + output.Key + thumbExt)
'Resize(item, thumbSeq, output.Value)
Next
Next
End Sub
End Class
%>
</body>
</html>

这是我遇到的错误:

Microsoft VBScript compilation error '800a03ea' 

Syntax error

/sandbox/aspjpeg/Default.asp, line 45

resizeValues = Dictionary(String, Integer)()
----------------------------------^

最佳答案

您需要重新考虑您正在做的很多事情。 .Net 不会逐行翻译成 vbscript,甚至不会逐个类/模块翻译成 vbscript。您必须查看 ASP.Net 实际在做什么,并弄清楚如何在 vbscript 中执行此操作。

vbscript 的一个技巧是,与其乱用 vbscript 文件 io 来处理配置文件,我发现通过在单独的文件中定义这些变量来处理配置数据要容易得多,然后将这些变量包含在其他地方。然后您可以像使用其他变量一样使用该数据。
