C# | Uri。擒纵数据串(串)法
原文:https://www . geeksforgeeks . org/c-sharp-uri-擒纵数据字符串-method/
乌利。擒纵数据串(字符串)方法用于将字符串转换为其转义表示。
语法:公共静态字符串擒纵数据串(string string to scape)； 在这里，需要绳子才能逃脱。
返回值:这个方法返回一个包含字符串的转义表示的字符串。
异常:如果 stringToEscape 为空，这个方法抛出 ArgumentNullException 。 和 UriFormatException 如果字符串的长度超过 32766 个字符。
下面的程序说明了 Uri 的使用。擒纵数据串(字符串)方法:
例 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
string address1 = "http://www.contoso.com/index.htm# search";
// 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);
}
}
}
Output:
Escaped string is : http%3A%2F%2Fwww.contoso.com%2Findex.htm%23search
示例 2: 适用于参数异常
// 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);
}
}
}
Output:
stringToEscape can not be null
Exception Thrown: System.ArgumentNullException
例 3: 为尿酸异常
// 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
StringBuilder address1 = new StringBuilder("http://www.contoso.com/index.htm# search");
// 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);
}
}
}
Output:
Length of stringToEscape should not exceed from 32766 characters.
Exception Thrown: System.UriFormatException
