Im testing an endpoint 1/test?P1=V1&P2=V2&P3=V3&P4=V4.
P- Parameters
V- ParameterValues in which all the ParameterValues can be null/empty.
So how to write a code in C# that drop the parameters if the ParameterValues are null and only hit the endpoint with the parameters having values in it.

You can use a dictionary, add all your parameters to it and then filter out only them which are not empty
Example:
Dictionary<string, string> parameters = new Dictionary<string, string>();
// add the parameters and their values
parameters.Add("P1", "V1");
parameters.Add("P2", "");
parameters.Add("P3", "V3");
parameters.Add("P4", null);
// filter out entries where the value is null or empty
var filteredParams = parameters.Where(x => !string.IsNullOrEmpty(x.Value));
// construct the query string from the remaining parameters
string queryString = string.Join("&", filteredParams.Select(p => $"{p.Key}={p.Value}"));
string endpoint = "https://example.com/v1/test";
string url = $"{endpoint}?{queryString}";

I am new to servicestack and using servicestack version 4.5.0.
With reference to the ServiceStack 'session' missing?
Where can I find this base.SessionBag property ? with base keyword I am getting
these intellisense
please help me.
what does this line means:
Inside a Service the dynamic untyped Session Bag was renamed to base.SessionBag.
what does this line means:
Inside a Service the dynamic untyped Session Bag was renamed to base.SessionBag.
when I write base. I find following intellisense
base.Session //-- Property Method
base.SaveSession //--- Extension
base.SessionAs<>
base.SessionFactory //-- Property Method
public class EntryService : Service
{
public object Post(Entry request)
{
var date = request.Time.Date;
var trackedData = (TrackedData)Session= date.ToString();
if(trackedData == null)
trackedData = new TrackedData { Goal = 300 };
trackedData.Total += request.Amount;
Session[date.ToString()] = trackedData;
return new EntryResponse { Id = 1};
}
}
i want like this
Session[date.ToString()] = trackedData;
but an error occurs Cannot apply indexing with [] to an expression of type ServiceStack.CacheAccess.ISession

You have to inherit from ServiceStack's Service base class. You can then access the dynamic Session Bag with base.SessionBag.

I got a enum like this:
public enum PlatForms
{
AAA=1,
BBB=2,
CCC=3
}
and a function like this:
public List<Something> GetSomething(PlatForms pf)
{
switch(pf)
{
case PlatForms.AAA:
var some = context.table1.Where(x => x.Prop == true);
break;
case PlatForms.BBB:
var some2 = context.table2.Where(x => x.Prop == true);
break;
default:
break;
}
//do convert;
//
}
The difference is table name is not same. How do I rewrite the code to make it simple?

Would something like this work?
You wouldn't want this Dictionary code to run every single time, so as soon as you have your context you could initialize a Dictionary...
var tableTranslation = new Dictionary<Platforms, Context>();
tableTranslation.Add(Platforms.AAA, context.table1);
tableTranslation.Add(Platforms.BBB, context.table2);
Then in your GetSomething() method you could just reference the Dictionary's table.
var some = tableTranslation[pf].Where(x => x.Prop == true);
//do convert
Would that do what you're looking for?

I am trying to create a c# method that can be reused multiple times,but depending on the condition of the variable type, i would like to be able to construct the name of a text field.
For example, if type="TY" then I would like to call
if ((String)this.TYIdlabelChange.Value == null)
However, if type="CA", then I would like to call
if ((String)this.CAIdlabelChange.Value == null)
Other examples:
if ((String)this.DIIdlabelChange.Value == null)
if ((String)this.LOIdlabelChange.Value == null)
if ((String)this.REIdlabelChange.Value == null)
etc...
Any ideas?
Thank you!

You need use Page.FindControl, something like this
var tb = FindControl(type+"IdlabelChange") as Textbox;
if(tb != null && tb.Value != null){
....
}

I have an object named 'Account' and the following code:
Account objAcc = new Account();
objAcc.Name = "Test";
The above is working fine, as expected. I now have a list of values as follows:
string props = "Name,Address,Telephone";
Now, what I want to do is see if "Name" exists in that list. I only have the object to use though (hard coding a case statement etc isn't possible as the object is dynamic), so from objAcc.Name, I somehow need to get "Name" from that, and then see if it's in the list.
Thanks in advance, I hope it's clear enough,
Dave

You can use reflection, by doing that :
var properties = objAcc.GetType().GetProperties();
foreach(var property in properties)
{
if(props.Contains(property.Name))
{
//Do you stuff
}
}

string test = objAcc.GetType().GetProperty("Name") == null ? "" : objAcc.GetType().GetProperty("Name").Name;
bool result = "Name,Address,Telephone".Split(',').Contains(test);
You may use the following method if you like:
public bool PropertyExists<T>(string propertyName, IEnumerable<string> propertyList,T obj)
{
string test = obj.GetType().GetProperty(propertyName) == null ? "" : obj.GetType().GetProperty(propertyName).Name;
bool result = propertyList.Contains(test);
return result;
}
