Initializes a new instance of the ResourceReader class for the specified stream.
Assembly: mscorlib (in mscorlib.dll)
Public Sub New ( _ stream As Stream _ )
public ResourceReader(
Stream stream
)
public:
ResourceReader(
Stream^ stream
)
new :
stream:Stream -> ResourceReader
Parameters
- stream
- Type: System.IO.Stream
The input stream for reading resources.
| Exception | Condition |
|---|---|
| ArgumentException |
The stream is not readable. |
| ArgumentNullException |
The stream parameter is null. |
| IOException |
An I/O error has occurred while accessing stream. |
The ResourceReader constructor instantiates a ResourceReader object that retrieves resources either from a standalone .resources file or from a .resources file that is embedded in an assembly. To read from a standalone .resources file, instantiate a Stream object and pass it to the ResourceReader constructor. To read from an embedded .resources file, call the Assembly.GetManifestResourceStream method with the case-sensitive name of the .resources file, and pass the returned Stream object to the ResourceReader constructor.
The example in this section uses the following .txt file named PatientForm.txt to define the resources used by an application.
Title="Top Pet Animal Clinic" Label1="Patient Number:" Label2="Pet Name:" Label3="Species:" Label4="Breed:" Label5="Date of Birth:" Label6="Age:" Label7="Owner:" Label8="Address:" Label9="Home Phone:" Label10="Work Phone:" Label11="Mobile Phone:"
You can compile the .txt file into a .resources file by issuing the following command:
resgen PatientForm.txt
The following example assumes that the resource file is embedded in the assembly that contains the application's executable code. It retrieves a resource file named PatientForm.resources from the currently executing assemblies and displays the name and value of each of its resources.
Imports System.Collections Imports System.IO Imports System.Reflection Imports System.Resources Module Example Public Sub Main() Dim assem As Assembly = Assembly.GetExecutingAssembly() Dim fs As Stream = assem.GetManifestResourceStream("PatientForm.resources") Dim rr As New ResourceReader(fs) Dim dict As IDictionaryEnumerator = rr.GetEnumerator Dim ctr As Integer Do While dict.MoveNext() ctr += 1 Console.WriteLine("{0:00}: {1} = {2}", ctr, dict.Key, dict.Value) Loop rr.Close() End Sub End Module ' The example displays the following output: ' 01: Label3 = "Species:" ' 02: Label2 = "Pet Name:" ' 03: Label1 = "Patient Number:" ' 04: Label7 = "Owner:" ' 05: Label6 = "Age:" ' 06: Label5 = "Date of Birth:" ' 07: Label4 = "Breed:" ' 08: Label9 = "Home Phone:" ' 09: Label8 = "Address:" ' 10: Title = "Top Pet Animal Clinic" ' 11: Label10 = "Work Phone:" ' 12: Label11 = "Mobile Phone:"
using System; using System.Collections; using System.IO; using System.Reflection; using System.Resources; public class Example { public static void Main() { var assem = Assembly.GetExecutingAssembly(); var fs = assem.GetManifestResourceStream("PatientForm.resources"); var rr = new ResourceReader(fs); IDictionaryEnumerator dict = rr.GetEnumerator(); int ctr = 0; while (dict.MoveNext()) { ctr++; Console.WriteLine("{0:00}: {1} = {2}", ctr, dict.Key, dict.Value); } rr.Close(); } } // The example displays the following output: // 01: Label3 = "Species:" // 02: Label2 = "Pet Name:" // 03: Label1 = "Patient Number:" // 04: Label7 = "Owner:" // 05: Label6 = "Age:" // 06: Label5 = "Date of Birth:" // 07: Label4 = "Breed:" // 08: Label9 = "Home Phone:" // 09: Label8 = "Address:" // 10: Title = "Top Pet Animal Clinic" // 11: Label10 = "Work Phone:" // 12: Label11 = "Mobile Phone:"
If the C# example is named Example.cs, you can compile it by using the following command:
csc Example.cs /res:PatientForm.resources
If the Visual Basic example is named Example.vb, you can compile it by using the following command:
vbc Example.vb /res:PatientForm.resources
