UriBuilder.Query Property (System)

.NET Framework Class Library

UriBuilder..::.Query Property

Gets or sets any query information included in the URI.

Namespace: System
Assembly: System (in System.dll)

Syntax

Visual Basic (Declaration)

Public Property Query As String

Visual Basic (Usage)

Dim instance As UriBuilder
Dim value As String

value = instance.Query

instance.Query = value

public string Query { get; set; }

Visual C++

public:
property String^ Query {
    String^ get ();
    void set (String^ value);
}

JScript

public function get Query () : String
public function set Query (value : String)

Property Value

Type: System..::.String
The query information included in the URI.

Remarks

The Query property contains any query information included in the URI. Query information is separated from the path information by a question mark (?) and continues to the end of the URI. The query information returned includes the leading question mark.

The query information is escaped according to RFC 2396.

Note In version 1.0 and 1.1 of the .NET Framework, setting the Fragment property to any value, including nullNothingnullptra null reference (Nothing in Visual Basic), cleared the Query property, and setting the Fragment property to nullNothingnullptra null reference (Nothing in Visual Basic) or to String..::.Empty cleared the property. In version 2.0, however, the Fragment and Query properties are independent.

Note Do not append a string directly to this property. If the length of Query is greater than 1, retrieve the property value as a string, remove the leading question mark, append the new query string, and set the property with the combined string.

Examples

The following example sets the Query property.

            UriBuilder baseUri = new UriBuilder("http://www.contoso.com/default.aspx?Param1=7890");
            string queryToAppend = "param2=1234";

            if (baseUri.Query != null && baseUri.Query.Length > 1)
                baseUri.Query = baseUri.Query.Substring(1) + "&" + queryToAppend; 
            else
                baseUri.Query = queryToAppend;

Visual C++

UriBuilder^ baseUri = gcnew UriBuilder 
    ("http://www.contoso.com/default.aspx?Param1=7890");
String^ queryToAppend = "param2=1234";
if (baseUri->Query != nullptr && baseUri->Query->Length > 1)
{
    baseUri->Query = baseUri->Query->Substring(1)+ "&" + queryToAppend;
}

else
{
    baseUri->Query = queryToAppend;
}
