Composite provider from interface . Given multiple implementation of an interface , return data from each / one
Add the nuget package to your project
dotnet add package RSCG_CompositeProvider
dotnet add package RSCG_CompositeProviderCommon
or put in your csproj file
<ItemGroup>
<PackageReference Include="RSCG_CompositeProvider" Version="2025.221.439" OutputItemType="Analyzer" ReferenceOutputAssembly="false" />
<PackageReference Include="RSCG_CompositeProvider_Common" Version="2025.221.439" />
</ItemGroup>Then if you have an interface like this
public interface IDataFrom
{
string Name { get; }
Task<string> KeyFromValue(string value, bool isKey);
}and multiple implementation of the interface like this
class DataFromHttp : IDataValue
{
public string Name { get { return "DataFromHttp"; } set { } }
public async Task<string> KeyFromValue(string key, bool defaultValue)
{
var http=new HttpClient();
var result = await http.GetStringAsync("https://www."+ Guid.NewGuid().ToString()+".com/" + key);
return result;
}
}
class DataFromMemory : IDataValue
{
public string Name { get { return "DataFromMemory"; } set { } }
public async Task<string> KeyFromValue(string key, bool defaultValue)
{
await Task.Delay(1000);
return $"this is value for {key} from memory";
}
}then you can call the composite provider to get data from all the implementation of the interface like this
IDataValue provider = new DataValue_CP(new DataFromHttp(), new DataFromMemory());
var result = await provider.KeyFromValue("test", false);
Console.WriteLine(result);
DataValue_CP realClass = (DataValue_CP)provider ;
var lastInterface = realClass.lastUsedInterface ?? -1;
Console.WriteLine("value was obtained from " + realClass.Get(lastInterface).Name);
