Question

我对存储库和模拟存储库相当新，所以我想帮助理解这个错误究竟意味着什么，以及如何避免它。我查看了其他帖子并完成了我的研究，但它们对于他们的错误太具体了。破解的代码是

public int PersistComponentDb(Core.Models.ComponentDbModel componentDb)
{
    return PersistComponentDb(componentDb);
}

我知道该函数正在调用自身，但是如何阻止它执行此操作？它持久存储模拟存储库，硬编码值看起来像这样

public DataTable GetComponentDbs(int? forComponentId = null, int? forDbServerId = null, int? forEntityId = null)
{
    DataTable componentDbs = new DataTable();
    componentDbs.Columns.Add("ComponentDbID", typeof(Int32));
    componentDbs.Columns.Add("ComponentID", typeof(Int32));
    componentDbs.Columns.Add("DbServerID", typeof(Int32));
    componentDbs.Columns.Add("EntityID", typeof(int));
    componentDbs.Columns.Add("SecurableGuid", typeof(String));
    componentDbs.Columns.Add("FriendlyName", typeof(String));
    componentDbs.Columns.Add("DbName", typeof(String));
    componentDbs.Rows.Add(new object[] { 1, 2, 2, 3822, "SecureableGuid", "Test #1", "DB #1" });
    return componentDbs;
}

public DataRow GetComponentDb(int id)
{
    DataTable componentDbs = new DataTable();   
    componentDbs.Columns.Add("ComponentDbID", typeof(Int32));
    componentDbs.Columns.Add("ComponentID", typeof(Int32));
    componentDbs.Columns.Add("DbServerID", typeof(Int32));
    componentDbs.Columns.Add("EntityID", typeof(Int32));
    componentDbs.Columns.Add("SecurableGuid", typeof(String));
    componentDbs.Columns.Add("FriendlyName", typeof(String));
    componentDbs.Columns.Add("DbName", typeof(String));
    componentDbs.Rows.Add(new object[] { 123, 121, 12, null, "SecurableGuid", "Name", "Database name" });
    return componentDbs.Rows[0];
}

PersistComponentDb后面的其余代码是

public int PersistComponentDb(ComponentDbModel componentDb)
{
    // Example implementation.
    return _repository.PersistComponentDb(componentDb);
}

和

int PersistComponentDb(ComponentDbModel componentDb);

这种方法自称。因此堆栈溢出。

public int PersistComponentDb(Core.Models.ComponentDbModel componentDb)
{
    return PersistComponentDb(componentDb);
}

这段代码应该是：

public int PersistComponentDb(Core.Models.ComponentDbModel componentDb)
{
    return _repository.PersistComponentDb(componentDb);
}

System.StackOverflowException未处理错误
