日期时间 object 不接受 dd/MM/yyyy 格式 ASP.NET 核心 Web API 和 C#

Question

I have a DateTime query parameter in an ASP.NET Core Web API, if I pass it a date with dd/MM/yyyy format, I get an error "invalid value".

Actually, on the front end, I am using Blazor WASM and it's sending the value in the dd/MM/yyyy format.

For now, I have to use string type and keep it formatted as MM/dd/yyyy or yyyy/MM/dd for API to accept. is there any other solution? I Want to use DateTime and not string can i get yyyy/MM/dd format from DateTime without converting it to string?

API Endpoint

[HttpGet]
public async Task<IActionResult> Get([FromQuery] DateTime date)
{
  return Ok(date);
}

You can use long data type for the DateTime exchange. This is Unix time which is UTC. Easy to exchange DateTime between server and client.

From the javascript client-side you can get Unix time like this.

var d = new Date();
var ut = d.getTime();

From the asp.net server

var ut = DateTimeOffset.Now.ToUnixTimeMilliseconds();
