实体框架 - 将表的列名称作为字符串数组

Question

如果我首先使用EF 5和数据库生成数据库的.edmx模型,如何获取实体列的列表？

using (var db = new ProjectNameContext())
{
    // string[] colNames = db.Users.
}

我正在寻找的是colNames [0] =="Id",colNames [1] =="FirstName"等.

Answer 1

怎么样:

var names = typeof(User).GetProperties()
                        .Select(property => property.Name)
                        .ToArray();

当然,这可以用于任何类型,而不仅仅是EF表.

Answer 2

var res = typeof(TableName).GetProperties()
                        .Select(property => property.Name)
                        .ToArray();

或者

var res = dbContext.Model.FindEntityType(typeof(TableName))
                           .GetProperties().Select(x => x.Relational().ColumnName)
                           .ToList();

var index = 0;    
var propertyInfo = res[index].PropertyInfo;

var columnName = res[index].Relational().ColumnName;
var propertyName = propertyInfo.Name;
var propertyValue = propertyInfo.GetValue(sourceObject); // NEED OBJECT TO GET VALUE
