## ConnectionParameterType enumeration

Specifies the parameter type of external connection

```csharp
public enum ConnectionParameterType
```

### Values

| Name | Value | Description |
| --- | --- | --- |
| Cell | `0` | Get the parameter value from a cell on each refresh. |
| Prompt | `1` | Prompt the user on each refresh for a parameter value. |
| Value | `2` | Use a constant value on each refresh for the parameter value. |

### Examples

```csharp
namespace AsposeCellsExamples
{
    using Aspose.Cells.ExternalConnections;
    using System;

    public class ExternalConnectionsClassConnectionParameterTypeDemo
    {
        public static void Run()
        {
            try
            {
                // Demonstrate creating and using ConnectionParameterType enum values
                ConnectionParameterType cellParam = ConnectionParameterType.Cell;
                ConnectionParameterType promptParam = ConnectionParameterType.Prompt;
                ConnectionParameterType valueParam = ConnectionParameterType.Value;

                // Display the enum values
                Console.WriteLine("Connection Parameter Types:");
                Console.WriteLine($"Cell: {cellParam}");
                Console.WriteLine($"Prompt: {promptParam}");
                Console.WriteLine($"Value: {valueParam}");

                // Demonstrate usage in a switch statement
                ConnectionParameterType testParam = ConnectionParameterType.Prompt;
                switch (testParam)
                {
                    case ConnectionParameterType.Cell:
                        Console.WriteLine("Parameter will get value from a cell");
                        break;
                    case ConnectionParameterType.Prompt:
                        Console.WriteLine("Parameter will prompt user for value");
                        break;
                    case ConnectionParameterType.Value:
                        Console.WriteLine("Parameter will use constant value");
                        break;
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error demonstrating ConnectionParameterType: {ex.Message}");
            }
        }
    }
}
```
