Utilisation DeleteLaunchTemplate avec un AWS SDK ou une CLI
Les exemples de code suivants illustrent comment utiliser DeleteLaunchTemplate.
Les exemples d’actions sont des extraits de code de programmes de plus grande envergure et doivent être exécutés en contexte. Vous pouvez voir cette action en contexte dans les exemples de code suivants :

/// <summary>
/// Delete a launch template by name.
/// </summary>
/// <param name="templateName">The name of the template to delete.</param>
/// <returns>Async task.</returns>
public async Task DeleteTemplateByName(string templateName)
{
try
{
await _amazonEc2.DeleteLaunchTemplateAsync(
new DeleteLaunchTemplateRequest()
{
LaunchTemplateName = templateName
});
}
catch (AmazonEC2Exception ec2Exception)
{
if (ec2Exception.ErrorCode == "InvalidLaunchTemplateName.NotFoundException")
