Problem Scenario:
There is an enum keeping track of operations to be performed on a table
Public Enum PartitionKey {
Createtask,
Updatetask,
Deletetask
}
User is entering the value for the operation to be performed and the code to check the value entered in switch case.
Switch (value)
{
case PartitionKey.Createtask.ToString():
{
Create();
break;
}
case PartitionKey.Updatetask.ToString():
{
Update();
break;
}
case PartitionKey.Deletetask.ToString():
{
Delete();
break;
}
}
and it displays as error as “.”
Solution: One of the possible implmentation is as below.
Public Enum PartitionKey: byte {
Createtask,
Updatetask,
Deletetask
}
Switch ((PartitionKey)(Int32.Parse(value)))
{
case PartitionKey.Createtask:
{
Create();
break;
}
case PartitionKey.Updatetask:
{
Update();
break;
}
case PartitionKey.Deletetask:
{
Delete();
break;
}
default:
{
break;
}
}
