HttpCapabilitiesBase.Version Property

Gets the full version number (integer and decimal) of the browser as a string.

Namespace:  System.Web.Configuration
Assembly:  System.Web (in System.Web.dll)

public string Version { get; }

Property Value

Type: System.String
The full version number of the browser as a string.

The Version property returns a string. In some scenarios, the Version property might contain letter characters, as in the case of a browser or client device that is a beta version such as "7.0b." To correctly get the version as a data type that can be used in a numeric comparison, concatenate the MajorVersion and MinorVersion property values.

The following code example shows how to determine the Version of the browser. The MajorVersion property and MinorVersion property are concatenated and the result is used to determine whether the browser version is greater than 5.01.

        String labelText = "";
        System.Web.HttpBrowserCapabilities myBrowserCaps = Request.Browser;
        if (Double.Parse(((System.Web.Configuration.HttpCapabilitiesBase)myBrowserCaps).Version, System.Globalization.CultureInfo.InvariantCulture) > 5.01)
            labelText = "Browser version is greater than 5.01.";
            labelText = "Browser version is less than or equal to 5.01.";

        Label1.Text = labelText;
