Exporter DataTable pour exceler NumberFormat Pourcentage Comment supprimer le symbole décimal supplémentaire C# numéro

Question

J'exporte un DataTable vers Excel et l'une des colonnes est un pourcentage calculé.

Je montre les données dans le formulaire dans un DataGridView, et formate les colonnes dans le code, qui affiche la valeur en pourcentage dans le format désiré, c'est-à-dire .99450294 serait 99,45%.

Lors de l'exportation, je peux exporter vers Excel et la même colonne affiche la même valeur, mais si la valeur résultante est 100%, elle affiche 100.% en ajoutant la décimale juste avant le signe de pourcentage. Comment puis-je supprimer ce symbole décimal pour les articles qui correspondent à la valeur 100% à l'exportation?

Voici mon code;

Essayez de changer le format numérique que #% .00 si vous voulez 100% sans décimale avoir une condition et avoir le format de nombre que #%
