如何获取客户端机器日期格式？

Question

I want to get client machine date format, my application is hosted on US machine.

Hosting Server date format: MM/dd/yyyy Local(Client) machine date format: dd/MM/yyyy

I want to get dd/MM/yyyy format which is the format of the client machine.

I have used the following code but it returns server date format(MM/dd/yyyy) but I want client machine date format(Local).

DateTimeFormatInfo info = new DateTimeFormatInfo
{
    ShortDatePattern = CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern
};

Can anyone please tell how to get client machine date format(dd/MM/yyyy)?

Answer 1

In MVC asp.net:

Frist put Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(Request.UserLanguages.FirstOrDefault()); into Application_BeginRequest

if you don't have Application_BeginRequest . Please click Global.asax in your project.

add new function in MvcApplication class

protected void Application_BeginRequest() {

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(Request.UserLanguages.FirstOrDefault()); }

now, you could use format of DateTime.Now with client machine

For Retrieving Client date format. I think java-script would be the best option

Try below code. I hope it will help.

getDateFormat(){
    // initialize date value "31st January 2019"
    var my_date = new Date(2019,0,31);
    console.log(my_date.toLocaleDateString());
    // Initialize variables
    var separator="";
    var first="";
    var second="";
    var third="";
    var date_parts = [];

    // get separator : "-", "/" or " ", format based on toLocaleDateString function        
    if (my_date.toLocaleDateString().split("-").length==3){
        separator = " - ";
        date_parts = my_date.toLocaleDateString().split("-");
    } 
    if (my_date.toLocaleDateString().split("/").length == 3) {
        separator = " / ";
        date_parts = my_date.toLocaleDateString().split("/");
    } 
    if (my_date.toLocaleDateString().split(" ").length == 3) {
        separator = " ";
        date_parts = my_date.toLocaleDateString().split(" ");
    } 

    // get first part        
    if (date_parts[0]==2019){
        first ="yyyy";
    } else if (date_parts[0] == 31){
        first = "dd";
    } else{
        if (date_parts[0].length<=2){
            first ="mm";
        }
        else{
            first="mmm";
        }
    }

    // get second part        
    if (date_parts[1] == 2019) {
        second = "yyyy";
    } else if (date_parts[1] == 31) {
        second = "dd";
    } else {
        if (date_parts[1].length <= 2) {
            second = "mm";
        }
        else {
            second = "mmm";
        }
    }

    // get third part        
    if (date_parts[2] == 2019) {
        third = "yyyy";
    } else if (date_parts[2] == 31) {
        third = "dd";
    } else {
        if (date_parts[2].length <= 2) {
            third = "mm";
        }
        else {
            third = "mmm";
        }
    }

    // assembly
    var format = first + separator + second + separator + third;
    console.log(format);
    return format;
}
