编辑ini文件

Question

我找到了一些与编辑ini文件的某个部分完美配合的代码,但它只选择了我要编辑的第一行实例.我知道我可以手动输入我想要开始编辑的代码中的所有索引,但是知道事情如何随着时间的推移而改变,可能会对ini文件进行更改,然后索引也会发生变化.有人能解释一下这个问题吗？

const string FileName = "File.ini";
string file= File.ReadAllText(FileName);

const string Pattern = @"pattern = (?<Number>)";

Match match = Regex.Match(config, Pattern, RegexOptions.IgnoreCase);

if (match.Success)
{
    int index = match.Groups["Number"].Index;

    string newText= **********;
    file = file.Remove(index, 21);
    file = file.Insert(index, newText);

    File.WriteAllText(FileName, file);
}

简单的方法是使用WritePrivateProfileString和GetPrivateProfileString功能的Kernel32.dll读取和写入INI文件.

例:

写给INI:

[DllImport("kernel32.dll", EntryPoint = "WritePrivateProfileString")]
public static extern long WriteValueA(string strSection, 
                                       string strKeyName, 
                                       string strValue, 
                                       string strFilePath);

用法:

 WriteValueA("SectionToWrite", "KeyToWrite", "Value", @"D:\INIFile.ini");

从INI阅读:

[DllImport("kernel32.dll", EntryPoint = "GetPrivateProfileString")]
public static extern int GetKeyValueA(string strSection, 
                                      string strKeyName, 
                                      string strEmpty, 
                                      StringBuilder RetVal, 
                                      int nSize, 
                                      string strFilePath);

用法:

StringBuilder temp = new StringBuilder(255);
int i = GetKeyValueA("TargetSection", "KeyToRead", string.Empty, temp, 255, @"D:\INIFile.ini");
string sValue = temp.ToString(); //desired value of the key
