WritePrivateProfileString 是一个函数,它用于向INI文件中写入或修改一个键值对。

它的用法如下: WritePrivateProfileString(section, key, value, filename)

参数说明:

函数的功能是将指定的键值对写入或修改INI文件中指定节下的指定键名处。如果指定的节或键名不存在,则函数会创建它们。

示例:

Imports System.Runtime.InteropServices

Public Class Form1
    <DllImport("kernel32")>
    Private Shared Function WritePrivateProfileString(section As String, key As String, value As String, filePath As String) As Integer
    End Function

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Dim section As String = "MySection"
        Dim key As String = "MyKey"
        Dim value As String = "MyValue"
        Dim filePath As String = "C:\path\to\my.ini"

        WritePrivateProfileString(section, key, value, filePath)
    End Sub
End Class

上述示例代码中,当按钮被点击时,会将 “MySection” 节下的 “MyKey” 键的值设置为 “MyValue”,并写入到 “C:\path\to\my.ini” 文件中。
