如何在 Entity Framework 6 中以编程方式创建与 MS SQL 的连接字符串?

How do I create connection string programmatically to MS SQL in Entity Framework 6?

我正在使用 c# 和 WPF，我想知道是否有人可以向我展示如何或将我链接到显示如何在 EF 6 中以编程方式设置连接字符串的资源.MSDN 文章解释说您可以 http://msdn.microsoft.com/en-us/data/jj680699#moving 但它没有进入创建实际的连接字符串.

I'm using c# and WPF and I was wondering if someone could show me how or link me to a resource that shows how to set up connection strings programmatically in EF 6. The MSDN article explains that you can http://msdn.microsoft.com/en-us/data/jj680699#moving but it doesn't go into creating actual connection strings.

所以这是一个有效的 EF6 示例

So here is an EF6 example that works

App.Config

entityFramework codeConfigurationType="WPFwithEF.SqlConfiguration, WPFwithEF">/实体框架

entityFramework codeConfigurationType="WPFwithEF.SqlConfiguration, WPFwithEF"> /entityFramework

上下文

public class ProductContext : DbContext
{  
    public ProductContext():base("Wpf")
    { }
    public DbSet<Category> Categories { get; set; }
    public DbSet<Product> Products { get; set; }
}

配置.cs

namespace WPFwithEF
{
public class SqlConfiguration : DbConfiguration
{

    public SqlConfiguration()
    {
        SetProviderServices(SqlProviderServices.ProviderInvariantName,SqlProviderServices.Instance);           
        SetDefaultConnectionFactory(new SqlConnectionFactory());
    }
}
}

但是如果上下文基础是name=Wpf"那么这个设置不起作用有没有办法让它起作用?而且我正在寻找最新的 EF6，而不是旧的方式.

but if the context base is "name=Wpf" then this set up does not work is there a way to make that work? And i'm looking for the latest EF6 not the old way to do it.

推荐答案

您可以使用 EntityConnectionStringBuilder，如下所述:如何:构建一个EntityConnection连接字符串

You can use the EntityConnectionStringBuilder as descriped here: How to: Build an EntityConnection Connection String
