我对Entity Framework还不熟悉,尝试向查找表中插入新项目时遇到了问题。
错误信息如下 -
"未处理的异常类型
System.StackOverflowException
出现在mscorlib.dll中"
该错误出现在最终的代码块中,即调用public DIEMEntities()
函数时。
每当我添加新项目时都会出现此错误,但我可以正常更新项目。
任何帮助将不胜感激。
以下是代码 -
protected void OnSave(object sender, EventArgs e)
{
ArrayList validationErrors = new ArrayList();
ContactTypeEO contactType = new ContactTypeEO();
if (uxID.Value.Length > 0)
{
//Updating
contactType.Id = int.Parse(uxID.Value);
}
contactType.Name = uxName.Text;
contactType.ExpressionValidator = uxExpression.Text;
contactType.Save(ref validationErrors);
if (validationErrors.Count > 0)
{
ShowValidationMessages(validationErrors);
}
else
{
this.RefreshUI();
}
}
public bool Save(ref ArrayList validationErrors)
{
ValidateSave(ref validationErrors);
if (validationErrors.Count == 0)
{
if (Id == 0)
{
ContactTypeData.Insert(Name, ExpressionValidator);
}
else
{
ContactTypeData.Update(Id, Name, ExpressionValidator);
}
return true;
}
else
{
return false;
}
}
/// <summary>

public static void Insert(string name, string validator)
{
using (DIEMEntities diemEntities = new DIEMEntities())
{
Insert(name, validator);
}
}

}
