  revit读取材料的外观信息不能通过lookup来搞定，所以读取起来稍微有点麻烦。但是在revit二次开发的官方基础教程里有相关的解释。

         这里就以一个墙体为例，读取墙体材料的所有外观信息（如下图）。这里主要针对autodesk的官方材料库来说的。对于非官方材料库的，下面的代码里被注释掉的可以参考一下。其实读取材料的原理比较简单，过程如下：

1)获取材料的ID，ICollection<ElementId> matId = elem.GetMaterialIds(true); 

2）// 读取revit标准材质库  
            AssetSet objlibraryAsset = revitApp.get_Assets(AssetType.Appearance);

3）从CompoundStructureLayer中获得材料

4）分两种情况读取材料。

}

这其中还有一个往数据库中读取材料性质的类，这个类有两个作用：

1）把材料放到数据库里

2）检查数据库里是否已经存在该材料的信息

其中下面这句代码是数据库的链接地址，依据个人的电脑不同而改变。

private string str = "Data Source=USER-20161016YAMEDICINE;Initial Catalog=MyMaterials;Integrated Security=True";

using System;
using System.Collections.Generic;
using System.Data.SqlClient;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 读取墙体材料
{
 
 public class ReadAssetProperty
 {
 private string str = "Data Source=USER-20161016YAMEDICINE;Initial Catalog=MyMaterials;Integrated Security=True";
 public void ReadAssetPropertyFromRevit(string materialId ,string paramName, string type,string value)
 {
 int n = -1;
 //连接数据库
 using (SqlConnection con = new SqlConnection(str))
 {
 //string sql = string.Format("insert into MaterialFormRevit(MaterialId,ParamName, MatType, Value) values('{0}','{1}','{2}',{3})", 1,paramName, type, value);
 string sql = string.Format("insert into MaterialFormRevit(MaterialId,ParamName, MatType, Value) values('{0}','{1}','{2}','{3}')", materialId, paramName, type, value);
 using (SqlCommand cmd = new SqlCommand(sql, con))
 {
 con.Open();
 n = cmd.ExecuteNonQuery();
 }
 }
 //string msg = n > 0 ? "操作成功" : "操作失败";
 //LoadData();//刷新数据
 }
 public bool CheckMaterialMxExists(string strMaterialId, string paramName)
 {
 bool flag = false; 
 SqlConnection mycon = new SqlConnection(str);
 //查询此编号是否存在
 mycon.Open();
 SqlCommand mycmd = new SqlCommand("select MaterialId from MaterialFormRevit where MaterialId='" + strMaterialId + "'AND ParamName='" + paramName + "'", mycon);
 SqlDataReader mysdr = mycmd.ExecuteReader();
 if (mysdr.HasRows)
 {
 flag = false;
 }
 else
 {
 flag = true;
 }
 mysdr.Close();
 mycon.Close();
 return flag;
 }
 }
 
}

其中中间过渡属性的材料如下

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 读取墙体材料
{
 public class Depart
 {
 private int _MaterialId;
 private string _ParamName;
 private string _Type;
 private string _Value;

 public int MaterialId
 {
 get
 {
 return _MaterialId;
 }

 set
 {
 _MaterialId = value;
 }
 }

 public string ParamName
 {
 get
 {
 return _ParamName;
 }

 set
 {
 _ParamName = value;
 }
 }

 public string Type
 {
 get
 {
 return _Type;
 }

 set
 {
 _Type = value;
 }
 }

 public string Value
 {
 get
 {
 return _Value;
 }

 set
 {
 _Value = value;
 }
 }
 }
}

最后Form的代码如下：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace 读取墙体材料
{
 public partial class Form1 : Form
 {
 public Form1()
 {
 InitializeComponent();
 }
 string str = "Data Source=USER-20161016YAMEDICINE;Initial Catalog=MyMaterials;Integrated Security=True";
 private void Form1_Load(object sender, EventArgs e)
 {
 LoadData();
 }
 private void LoadData()
 {
 List<Depart> list = new List<Depart>();
 //通过连接字符串连接数据库
 using (SqlConnection con = new SqlConnection(str))
 {

 //拼接sql语句
 string sql = "select * from MaterialFormRevit";
 //准备执行sql语句的对象
 using (SqlCommand cmd = new SqlCommand(sql, con))
 {
 con.Open();//打开数据库
 //准备读数据
 using (SqlDataReader reader = cmd.ExecuteReader())
 {
 //判断是否有数据(有没有行)
 if (reader.HasRows)
 {

 //读取每一行
 while (reader.Read())
 {

 Depart dk = new Depart();//创建部门对象
 // dk.MaterialId= Convert.ToInt32(reader["MaterialId"]);
 dk.MaterialId =Convert.ToInt32(reader["MaterialId"].ToString()) ;
 dk.ParamName = reader["ParamName"].ToString();
 dk.Type = reader["MatType"].ToString();
 dk.Value = reader["Value"].ToString();

 list.Add(dk);//添加到集合中


 }//end while
 }//end if
 }// end sqldatareader
 }//end using
 }//end using


 dgv.AutoGenerateColumns = false;//禁止自动生成列
 dgv.DataSource = list;//绑定数据
 //dgv.SelectedRows[0].Selected = false;//禁止被选中

 }
 }
}
