Uri.EscapeDataString(String) Method is used to convert a string to its escaped representation.
Syntax: public static string EscapeDataString (string stringToEscape);
Here, it takes the string to escape.Return Value: This method returns a string which contains the escaped representation of stringToEscape.
Exception: This method throws ArgumentNullException if stringToEscape is null.
and UriFormatException if The length of stringToEscape exceeds 32766 characters.
Below programs illustrate the use of Uri.EscapeDataString(String) Method:
Example 1:
// C# program to demonstrate the // Uri.EscapeDataString(String) Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing address1
// Converting a string to its
// escaped representation
// using EscapeDataString() method
string value = Uri.EscapeDataString(address1);
// Displaying the result
Console.WriteLine( "Escaped string is : {0}" , value);
}
catch (ArgumentNullException e)
{
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
} |

Example 2: For ArgumentNullException
// C# program to demonstrate the // Uri.EscapeDataString(String) Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing address1
string address1 = null ;
// Converting a string to its
// escaped representation
// using EscapeDataString() method
string value = Uri.EscapeDataString(address1);
// Displaying the result
Console.WriteLine( "Escaped string is : {0}" , value);
}
catch (ArgumentNullException e)
{
Console.WriteLine( "stringToEscape can not be null" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (UriFormatException e)
{
Console.WriteLine( "Length of stringToEscape should" +
" not exceed from 32766 characters." );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}

stringToEscape can not be null Exception Thrown: System.ArgumentNullException
Example 3: For UriFormatException
// C# program to demonstrate the // Uri.EscapeDataString(String) Method using System;
using System.Text;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// Declaring and initializing address1
// appending StringBuilder
for ( int i = 1; i <= 3000; i++)
address1.Append( "abcedfghijklmnopdjdjdjdjdjjddjjdjdj" );
// Converting a string to its
// escaped representation
// using EscapeDataString() method
string value = Uri.EscapeDataString(address1.ToString());
// Displaying the result
Console.WriteLine( "Escaped string is : {0}" , value);
}
catch (ArgumentNullException e)
{
Console.WriteLine( "stringToEscape can not be null" );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
catch (UriFormatException e)
{
Console.WriteLine( "Length of stringToEscape should" +
" not exceed from 32766 characters." );
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
