Usage

Find an entity by key

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

// find by key
var role = await roleRepo.FindAsync("67a0dc52fa5ebe49f293a374");

Find one entity with query

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

// find one by query expression
var role = await roleRepo.FindOneAsync(r => r.Name.StartsWith("Admin"))

Find many with query

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

// find one by query expression
var roles = await roleRepo.FindAllAsync(r => r.Name.StartsWith("Admin"))

Use IQueryable

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

// Use IQueryable
var roles = roleRepo.All()
    .Where(r => r.IsActive)
    .ToList();

Insert entity

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

var role = new Role { Name = "CreateReadRole" };

var createdRole = await roleRepo.InsertAsync(role);

Update entity

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

// find by key
var role = await roleRepo.FindAsync("67a0dc52fa5ebe49f293a374");

// make changes
role.Name = "UpdateRole";

var updateRole = await roleRepo.UpdateAsync(role);

Delete entity by key

// dependency inject
var roleRepo = Services.GetRequiredService<IMongoEntityRepository<Role>>();

// items deleted
var count = await roleRepo.DeleteAsync("67a0dc52fa5ebe49f293a374");
