C#如何读取写在ini中的数据库连接字符串

Question

如题所述

Answer 1

给你一个类，可以直接读取INI文件中东西

public class IniFile
{
/// <summary>
/// ini文件名称（带路径)
/// </summary>
public string filePath;

//声明读写INI文件的API函数
[DllImport("kernel32")]
private static extern long WritePrivateProfileString(string section, string key, string val, string filePath);

[DllImport("kernel32")]
private static extern int GetPrivateProfileString(string section, string key, string def, StringBuilder retVal, int size, string filePath);

/// <summary>
/// 类的构造函数
/// </summary>
/// <param name="INIPath">INI文件名</param>
public IniFile(string INIPath)
{
filePath = INIPath;
}

/// <summary>
/// 写INI文件
/// </summary>
/// <param name="Section">Section</param>
/// <param name="Key">Key</param>
/// <param name="value">value</param>
public void WriteInivalue(string Section, string Key, string value)
{
WritePrivateProfileString(Section, Key, value, this.filePath);

}

/// <summary>
/// 读取INI文件指定部分
/// </summary>
/// <param name="Section">Section</param>
/// <param name="Key">Key</param>
/// <returns>String</returns>
public string ReadInivalue(string Section, string Key)
{
StringBuilder temp = new StringBuilder(255);
int i = GetPrivateProfileString(Section, Key, "", temp, 255, this.filePath);
return temp.ToString();

}

这个文件是文本格式的,用读取文本文件流的方式就可以读出来.
