How can I parse Kusto timespan strings in C#?

Question

I tried TimeSpan.Parse("2d") , for example, but that doesn't work.

The format of Kusto timespan doesn't seem to be supported by any of the TimeSpan.Parse() flavors.

Answer 1

The Kusto Data Client SDK for .NET (in the Microsoft.Azure.Kusto.Data nuget package) has a CslTimeSpanLiteral class that understands this format. It contains several static methods for parsing strings to .NET's TimeSpan structure.

For example:

using Kusto.Data.Common;

...

TimeSpan? ts = CslTimeSpanLiteral.Parse("2d");

In addition to Parse , there is also ParseNoNull , TryParse , and TryParseNoNull .

Answer 2

TimeSpan.Parse in c# does not recognize the Kusto timespan strings like 2d,2h etc.

We don't know your purpose on parsing it, but you can use some code like below:

        string mytime = "2d";

        if (mytime.EndsWith("d"))
        {
            mytime = mytime.Remove(mytime.IndexOf('d'));
            var dt = DateTime.Now.AddDays(Convert.ToDouble(mytime));
            Console.WriteLine(dt.ToString());
        }
