//DeviseRepository 

namespace WebApplication6 
    { 
     public class DeviseRepository : IDeviseRepository 
    { 
     public IMongoDatabase db; 
     public DeviseRepository() 
     { 
     MongoClientSettings settings = new MongoClientSettings(); 
     settings.Server = new MongoServerAddress("localhost", 27017); 
     MongoClient client = new MongoClient(settings); 
     this.db = client.GetDatabase("bigdata"); 
     var collection = db.GetCollection<Devise>("Devise"); 

     } 


    public IMongoCollection<Devise> Devise 
    { 
     get 
     { return db.GetCollection<Devise>("Devise"); } 
    } 

    public Devise Add(Devise devise) 
    { 
     var collection = db.GetCollection<Devise>("Devise"); 
     collection.InsertOne(devise); 
     return devise; 
    } 

    public void MongoGoNow() 
    { 
     var collection = db.GetCollection<Devise>("devise"); 
     var result = TestFind(collection); 
     result.GetAwaiter().GetResult(); 
    } 

    static async Task TestFind(IMongoCollection<Devise> MyCollection) 
    { 
     var filter = new BsonDocument(); 
     var count = 0; 
     using (var cursor = await MyCollection.FindAsync(filter))

    public void insertdata() 
     { 
     var devise = new Devise(); 
     devise.parité = "euro/dollar"; 
     Devise.InsertOne(devise); 
     } 
    }

試試你插入更新到：

public void insertdata() 
{ 
    try 
    { 
     var devise = new Devise(); 
     devise.parité = "euro/dollar"; 
     Devise.InsertOne(devise); 
    } 
    catch (Exception ex) 
    { 
     //put a breakpoint here 
    } 
}
