Issue in Matching Department Name while using Microsoft Graph API V1.0

问题

I am using below code to match Department Name:

string departmentName = "Admin";

var departmentPeoples = await graphServiceClient.Users.Request().Filter($"department eq '{departmentName}'").Select(u => new {
    u.DisplayName,
    u.MobilePhone,
    u.BusinessPhones,
    u.UserPrincipalName
}).GetAsync();

This works, but when my search string is Admin & IT ,it doesn't work because of & sign. I tried using var departmentname ="Admin \& IT" But still it shows error:

Microsoft.Graph.ServiceException: 'Code: BadRequest Message: Invalid filter clause or string doesn't match.

回答1:

Try to convert "&" to "%26" manually.

You could use var departmentname ="Admin %26 IT" in this case.
