Note - 'MyResult.ResultParameterSortedList[(int)PassOfNorms.PassingCriteriaIDs.My_Name]' threw an exception of type 'System.Collections.Generic.KeyNotFoundException'
The `KeyNotFoundException` error indicates that the key `(int)PassOfNorms.PassingCriteriaIDs.My_Name` does not exist in the `MyResult.ResultParameterSortedList` dictionary or sorted list. Here’s how you can troubleshoot and fix this issue:
1. Check if the Key Exists Before Accessing:
Before assigning the value, you can check if the key exists in the dictionary or sorted list using `ContainsKey` (for a dictionary) or `Contains` (for a sorted list).
For Dictionary:
if (MyResult.ResultParameterSortedList.ContainsKey((int)PassOfNorms.PassingCriteriaIDs.My_Name))
{
MyResult.ResultParameterSortedList[(int)PassOfNorms.PassingCriteriaIDs.My_Name].Name = "Max Power (Kw)";
}
else
{
// Handle the case where the key does not exist
Console.WriteLine("Key not found: My_Name");
}
For SortedList:
if (MyResult.ResultParameterSortedList.Contains((int)PassOfNorms.PassingCriteriaIDs.My_Name))
{
MyResult.ResultParameterSortedList[(int)PassOfNorms.PassingCriteriaIDs.My_Name].Name = "Max Power (Kw)";
}
else
{
// Handle the case where the key does not exist
Console.WriteLine("Key not found: My_Name");
}
2. Ensure the Key is Added:
If the key is expected to be in the list but isn't, you might need to add it first:
if (!MyResult.ResultParameterSortedList.ContainsKey((int)PassOfNorms.PassingCriteriaIDs.My_Name))
{
// Create a new object with the appropriate type and add it to the list
MyResult.ResultParameterSortedList[(int)PassOfNorms.PassingCriteriaIDs.My_Name] = new ResultParameter { Name = "Max Power (Kw)" };
}
else
{
MyResult.ResultParameterSortedList[(int)PassOfNorms.PassingCriteriaIDs.My_Name].Name = "Max Power (Kw)";
}
3. Debugging:
- Check the Initialization: Ensure that `MyResult.ResultParameterSortedList` is properly initialized and populated with all expected keys before you attempt to access them.
- Inspect the Enumeration: Make sure that `PassOfNorms.PassingCriteriaIDs.My_Name` corresponds to a valid and correct value.
4. Exception Handling:
If you're unsure whether the key will be there and you want to handle it gracefully, you can wrap the code in a try-catch block:
try
{
MyResult.ResultParameterSortedList[(int)PassOfNorms.PassingCriteriaIDs.My_Name].Name = "Max Power (Kw)";
}
catch (KeyNotFoundException)
{
Console.WriteLine("Key not found: My_Name");
}
This approach ensures that your application doesn’t crash and gives you a chance to handle the missing key scenario appropriately.
