Does C# have an equivalent to JavaScript's encodeURIComponent()?

Question

Uri.EscapeDataString or HttpUtility.UrlEncode is the correct way to escape a string meant to be part of a URL.

Take for example the string "Stack Overflow":

• HttpUtility.UrlEncode("Stack Overflow") --> "Stack+Overflow"

• Uri.EscapeUriString("Stack Overflow") --> "Stack%20Overflow"

• Uri.EscapeDataString("Stack + Overflow") --> Also encodes "+" to "%2b" ---->Stack%20%2B%20%20Overflow

Only the last is correct when used as an actual part of the URL (as opposed to the value of one of the query string parameters)

HttpUtility.HtmlEncode / Decode
HttpUtility.UrlEncode / Decode

You can add a reference to the System.Web assembly if it's not available in your project

I tried to do full compatible analog of javascript's encodeURIComponent for c# and after my 4 hour experiments I found this

c# CODE:

string a = "!@#$%^&*()_+ some text here али мамедов баку";
a = System.Web.HttpUtility.UrlEncode(a);
a = a.Replace("+", "%20");

the result is: !%40%23%24%25%5e%26*()_%2b%20some%20text%20here%20%d0%b0%d0%bb%d0%b8%20%d0%bc%d0%b0%d0%bc%d0%b5%d0%b4%d0%be%d0%b2%20%d0%b1%d0%b0%d0%ba%d1%83

After you decode It with Javascript's decodeURLComponent();

you will get this: !@#$%^&*()_+ some text here али мамедов баку

Thank You for attention

System.Uri.EscapeUriString() didn't seem to do anything, but System.Uri.EscapeDataString() worked for me.

Try Server.UrlEncode(), or System.Web.HttpUtility.UrlEncode() for instances when you don't have access to the Server object. You can also use System.Uri.EscapeUriString() to avoid adding a reference to the System.Web assembly.

For a Windows Store App, you won't have HttpUtility. Instead, you have:

For an URI, before the '?':

• System.Uri.EscapeUriString("example.com/Stack Overflow++?")
  • -> "example.com/Stack%20Overflow++?"

For an URI query name or value, after the '?':

• System.Uri.EscapeDataString("Stack Overflow++")
  • -> "Stack%20Overflow%2B%2B"

For a x-www-form-urlencoded query name or value, in a POST content:

• System.Net.WebUtility.UrlEncode("Stack Overflow++")
  • -> "Stack+Overflow%2B%2B"
