C# 读写ini配置文件

C# 读写ini配置文件
1、新建类，引入命名空间 using System.Runtime.InteropServices;
2、声明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);

3、实现：写

/// <summary> 
/// 写入INI文件 
/// </summary> 
/// <param name="field">项目名称(如 [TypeName] )</param> 
/// <param name="Key">键</param> 
/// <param name="Value">值</param> 
public void GetValueOfKey(string field, string Key, string Value)
{
	WritePrivateProfileString(field, Key, Value, iniFilePath);
}

4、实现：读

/// <summary> 
/// 读出INI文件 
/// </summary> 
/// <param name="field">项目名称(如 [TypeName] )</param> 
/// <param name="Key">键</param>
