ASP.NET 2.0讀取設定檔範例程式碼

1. 核心類檔案 INIFILE.cs 代碼

1 /// ＜summary＞
2 /// INIFILE 操作類
3 /// ＜/summary＞
4 public class INIFILE
5 {
6 [DllImport("kernel32")]
7 private static extern long WritePrivateProfileString(string section,string key,string val,string filePath);
8
9 [DllImport("kernel32")]
10 private static extern int GetPrivateProfileString(string section,string key,string def, StringBuilder retVal,int size,string filePath);
11
12 //要訪問的檔案路徑
13 private string strFilePath;
14
15 public string FilePath
16 {
17 get { return strFilePath; }
18 set { strFilePath = value; }
19 }
20
21 public INIFILE()
22 {
23 }
24
25 public INIFILE( string strFilePath )
26 {
27 this.strFilePath = strFilePath;
28 }
29
30 public void WriteValue(string strSection,string strKey,string strValue)
31 {
32 if (FilePath.Length == 0)
33 {
34 throw new Exception("沒有設定路徑");
35 }
36 WritePrivateProfileString(strSection, strKey, strValue, this.FilePath);
37 }
38
39 public string ReadValue(string strSection,string strKey)
40 {
　　41 if (FilePath.Length == 0)
42 {
43 throw new Exception("沒有設定路徑");
44 }
45 StringBuilder sb = new StringBuilder();
46 int i = GetPrivateProfileString(strSection, strKey, "", sb, 255, this.FilePath);
47 return sb.ToString();
48 }
49 }

2. 後台調用檔案 INIFile.aspx.cs 代碼

1 protected void Page_Load(object sender, EventArgs e)
2 {
3 //Read
4 INIFILE ini = new INIFILE();
5 ini.FilePath = Request.PhysicalApplicationPath + "ini.ini";
6 string strReturnValue = ini.ReadValue("Annabelle", "Time");
7 Response.Write(strReturnValue);
8
9 //Write
10 INIFILE ini = new INIFILE();
11 ini.FilePath = Request.PhysicalApplicationPath + "ini.ini";
12 string strReturnValue = ini.ReadValue("Annabelle", "Time");
13 Response.Write(strReturnValue);
14 ini.WriteValue("Annabelle", "Time", "0");
15 strReturnValue = ini.ReadValue("Annabelle", "Time");
16 Response.Write(strReturnValue);
17 }
