Remarks

A local storage resource is a reserved directory in the file system of the virtual machine in which an instance of a role is running. To define a local storage resource for your hosted service, you must add a LocalResources element with LocalStorage elements to the ServiceDefinition.csdef file of the hosted service for each directory that you want to create. For more information about defining local storage resources, see the Configure Local Storage Resources.

After you define the local storage resources in the ServiceDefinition.csdef file, you can access the directories by using the properties defined in the LocalResource class. The following code example shows how you can write text to a file in the local storage resource:

// Retrieve an object that points to the local storage resource
LocalResource localResource = RoleEnvironment.GetLocalResource("localStoreTwo");

//Define the file name and path
string[] paths = { localResource.RootPath, "MyStorageTest.txt"};
String filePath = Path.Combine(paths);

using (FileStream writeStream = File.Create(filePath))
{
   Byte[] textToWrite = new UTF8Encoding(true).GetBytes("Testing Web role storage");
   writeStream.Write(textToWrite, 0, textToWrite.Length);
}
using (StreamReader streamReader = File.OpenText(filePath)
{
   string fileText = "";
   while ((fileText = streamReader.ReadLine()) != null)
   {
      Trace.WriteLine("The text from the file is: " + fileText, "Information");
   }
}
