HtmlInputFile.Value Property

Gets the full path of the file on the client's computer.

Namespace:  System.Web.UI.HtmlControls
Assembly:  System.Web (in System.Web.dll)

public override string Value { get; set; }

Property Value

Type: System.String
The full path of the client's file.


An attempt was made to assign a value to this property.

The Value property retrieves the full path of the file on the client's computer (for example "C:\MyFiles\Test.txt"). This is useful when you need to know where the file is stored on the computer submitting the file. This property is also commonly used to determine the original file name. To get the original file name, parse the value of this property.


The Value property is read-only. If you attempt to assign a value to this property, a System.NotSupportedException is thrown.

The following code example demonstrates how to use the Value property to display the full path of the file on the client's computer. For this example to work properly, you need to create a directory called Temp on your computer's drive C.
