Uri.IsWellFormedOriginalString() Method is used to show whether the string used to construct this Uri was well-formed and is not required to be further escaped.
Syntax: public bool IsWellFormedOriginalString ();
Return Value: This method returns true if the string was well-formed otherwise, false.
Below programs illustrate the use of Uri.IsWellFormedOriginalString() Method:
Example 1:
// C# program to demonstrate the // Uri.IsWellFormedOriginalString() // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
// Declaring and initializing address
// Validating if Uri is well formed or not
// using IsWellFormedOriginalString() method
bool value = address1.IsWellFormedOriginalString();
// Displaying the result
if (value)
Console.WriteLine( "uri is well formed" );
else
Console.WriteLine( "uri is not well formed" );
}
} |
Output:
uri is well formed
Example 2:
// C# program to demonstrate the // Uri.IsWellFormedOriginalString() // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// calling get() method
// if The string is not correctly escaped.
// The string is an absolute Uri
// that represents an implicit
// file Uri.
get ( new Uri( "c:\\directory\filename" ));
// The string is an absolute URI that
// is missing a slash before the path.
// The parser for the Uri.Scheme indicates
// that the original string was not well-formed.
// The string contains unescaped backslashes
// even if they are treated as forwarding slashes.
get ( new Uri( "http:\\host/path/file" ));
// The string represents a hierarchical
// absolute Uri and does not contain "://".
get ( new Uri( "www.contoso.com/path/file" ));
}
catch (UriFormatException e)
{
Console.Write( "uri is so poorly formed that system thrown " );
Console.Write( "{0}" , e.GetType(), e.Message);
Environment.Exit(1);
}
}
// defining get() method
public static void get (Uri address)
{
// Validating if Uri is well formed or not
// using IsWellFormedOriginalString() method
bool value = address.IsWellFormedOriginalString();
// Displaying the result
if (value)
Console.WriteLine( "uri is well formed" );
else
Console.WriteLine( "uri is poorly formed" );
}
} |
Output:
uri is well formed uri is poorly formed uri is poorly formed uri is poorly formed uri is well formed uri is so poorly formed that system thrown System.UriFormatException
