问题
Since I installed the new Windows Azure SDK 2.3 I got a warning from csrun:
"DevStore interaction through CSRun has been depricated. Use WAStorageEmulator.exe instead."
So there are two questions: 1) How to start the new storage emulator correctly from code? 2) How to determine from code if the storage emulator is already running?
回答1:
I found the solution myself. Here is my C# code. The old code used for SDK 2.2 is commented out.
public static void StartStorageEmulator()
{
//var count = Process.GetProcessesByName("DSServiceLDB").Length;
//if (count == 0)
// ExecuteCSRun("/devstore:start");
var count = Process.GetProcessesByName("WAStorageEmulator").Length;
if (count == 0)
ExecuteWAStorageEmulator("start");
}
/*
private static void ExecuteCSRun(string argument)
{
var start = new ProcessStartInfo
{
Arguments = argument,
FileName = @"c:\Program Files\Microsoft SDKs\Windows Azure\Emulator\csrun.exe"
};
var exitCode = ExecuteProcess(start);
Assert.AreEqual(exitCode, 0, "Error {0} executing {1} {2}", exitCode, start.FileName, start.Arguments);
}
*/
private static void ExecuteWAStorageEmulator(string argument)
{
var start = new ProcessStartInfo
{
Arguments = argument,
FileName = @"c:\Program Files (x86)\Microsoft SDKs\Windows Azure\Storage Emulator\WAStorageEmulator.exe"
};
var exitCode = ExecuteProcess(start);
Assert.AreEqual(exitCode, 0, "Error {0} executing {1} {2}", exitCode, start.FileName, start.Arguments);
}
private static int ExecuteProcess(ProcessStartInfo start)
{
int exitCode;
using (var proc = new Process { StartInfo = start })
{
proc.Start();
proc.WaitForExit();
exitCode = proc.ExitCode;
}
return exitCode;
}

using Xunit;
namespace UnitTests.Persistence
{
public class AzureStorageEmulatorManagerV3
{
private const string ProcessName = "WAStorageEmulator";
public static void StartStorageEmulator()
{
var count = Process.GetProcessesByName(ProcessName).Length;
if (count == 0)
ExecuteWAStorageEmulator("start");
}
public static void StopStorageEmulator()
{
Process process = GetWAstorageEmulatorProcess();
if (process != null)
{
process.Kill();
}
}
private static void ExecuteWAStorageEmulator(string argument)
{
var start = new ProcessStartInfo
{
Arguments = argument,
FileName = @"c:\Program Files (x86)\Microsoft SDKs\Windows Azure\Storage Emulator\WAStorageEmulator.exe"
};
var exitCode = ExecuteProcess(start);
if (exitCode != 0)
{
string message = string.Format(
"Error {0} executing {1} {2}",
exitCode,
start.FileName,
start.Arguments);
throw new InvalidOperationException(message);
}
}
private static int ExecuteProcess(ProcessStartInfo start)
{
int exitCode;
using (var proc = new Process { StartInfo = start })
{
proc.Start();
proc.WaitForExit();
exitCode = proc.ExitCode;
}
return exitCode;
}
public static Process GetWAstorageEmulatorProcess()
{
return Process.GetProcessesByName(ProcessName).FirstOrDefault();
}
[Fact]
public void StartingAndThenStoppingWAStorageEmulatorGoesOk()
{
// Arrange Start
AzureStorageEmulatorManagerV3.StartStorageEmulator();
// Act
Thread.Sleep(2000);
Process WAStorageEmulatorProcess = GetWAstorageEmulatorProcess();
// Assert
Assert.NotNull(WAStorageEmulatorProcess);
Assert.True(WAStorageEmulatorProcess.Responding);
// Arrange Stop
AzureStorageEmulatorManagerV3.StopStorageEmulator();
Thread.Sleep(2000);
// Act
WAStorageEmulatorProcess = GetWAstorageEmulatorProcess();
// Assert
Assert.Null(WAStorageEmulatorProcess);
}
}
}
回答3:
See my answer here. It actually uses the WAStorageEmulator status API instead of simply relying on testing whether or not the process exists as in @huha's own answer.
回答4:
See my answer here. It uses a neat little NuGet package to assist with starting/stopping the Azure Storage Emulator programmatically: RimDev.Automation.StorageEmulator.
