[ACCEPTED]-How can I remove white-spaces from ASP.NET MVC# output?-asp.net-mvc-3
I found my answer and create a final solution 5 like this:
First create a base-class to force 4 views to inherit from that, like below, and 3 override some methods:
public abstract class KavandViewPage < TModel > : System.Web.Mvc.WebViewPage < TModel > {
public override void Write(object value) {
if (value != null) {
var html = value.ToString();
html = REGEX_TAGS.Replace(html, "> <");
html = REGEX_ALL.Replace(html, " ");
if (value is MvcHtmlString) value = new MvcHtmlString(html);
else value = html;
}
base.Write(value);
}
public override void WriteLiteral(object value) {
if (value != null) {
var html = value.ToString();
html = REGEX_TAGS.Replace(html, "> <");
html = REGEX_ALL.Replace(html, " ");
if (value is MvcHtmlString) value = new MvcHtmlString(html);
else value = html;
}
base.WriteLiteral(value);
}
private static readonly Regex REGEX_TAGS = new Regex(@">\s+<", RegexOptions.Compiled);
private static readonly Regex REGEX_ALL = new Regex(@"\s+|\t\s+|\n\s+|\r\s+", RegexOptions.Compiled);
}
Then we should make 2 some changes in web.config file that located in Views folder 1 -see here for more details.
<system.web.webPages.razor>
<host factoryType="System.Web.Mvc.MvcWebRazorHostFactory, System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
<pages pageBaseType="Kavand.Web.Mvc.KavandViewPage"> <!-- pay attention to here -->
<namespaces>
<add namespace="System.Web.Mvc" />
....
</namespaces>
</pages>
</system.web.webPages.razor>
one way you can, is that create a custom 4 view page's inheritance; in that, override 3 Write() methods (3 methods will be founded), and 2 in these methods, cast objects to strings, remove white-spaces, and 1 finally call the base.Write();
You could use the String.Replace method:
string input = "This is text with ";
string result = input.Replace(" ", "");
or use a Regex 2 if you want to remove also tabs and new 1 lines:
string input = "This is text with far too much \t " + Environment.NewLine +
"whitespace.";
string result = Regex.Replace(input, "\\s+", "");
