[c#]:如何在C＃中读写INI文件(五)

this.Controls.AddRange ( new System.Windows.Forms.Control [ ] {

this.button3 ,

this.textBox4 ,

this.textBox3 ,

this.textBox2 ,

this.button2 ,

this.textBox1 ,

this.button1 ,

this.label3 ,

this.label2 ,

this.label1 } ) ;

this.MaximizeBox = false ;

this.Name = "Form1" ;

this.Text = "C＃操作INI文件--写操作" ;

this.ResumeLayout ( false ) ;

}

[STAThread]

static void Main ( )

{

Application.Run ( new Form1 ( ) ) ;

}

private void button1_Click ( object sender , System.EventArgs e )

{

openFileDialog1.ShowDialog ( ) ;

textBox1.Text = openFileDialog1.FileName ;

}

//写入INI文件

private void button2_Click ( object sender , System.EventArgs e )

{

string FileName = textBox1.Text ;

string section = textBox2.Text ;

string key = textBox3.Text ;

string keyValue = textBox4.Text ;

WritePrivateProfileString ( section , key , keyValue , FileName ) ;

MessageBox.Show ( "成功写入INI文件！" , "信息" ) ;

}

//读取指定INI文件的特定段落中的关键字的数值

private void button3_Click ( object sender , System.EventArgs e )

{

StringBuilder temp = new StringBuilder ( 255 ) ;

string FileName = textBox1.Text ;

string section = textBox2.Text ;

string key = textBox3.Text ;

int i = GetPrivateProfileString ( section , key ,

"无法读取对应数值！" , emp , 255 , FileName ) ;

//显示读取的数值

textBox4.Text = temp.ToString ( ) ;

}

}

}


总结



通过上面的这些介绍，可以看成C＃操作INI文件的过程，其实就是C＃调用Win32的API函数的过程。掌握了如何在C＃申明Win32的API函数，再来操作INI就显得非常简单。
