我需要转换此mysql表：
FirstName | LastName | Street | City | State | Zipcode | Contact Number
----------+----------+-------------+---------+-------+---------+----------------
John | Doe | 123 W. Main | Chicago | IL | 60600 | (312)555-7458
Jane | Doe | 321 W. Main | Chicago | IL | 60600 | (312)555-6628
到datagridview中的此表：
Name | Address | Contact Name
---------+-------------------------------+--------------
John Doe | 123 W. Main Chicago, IL 60600 | (312)555-7458
Jane Doe | 321 W. Main Chicago, IL 60600 | (312)555-6628
我尝试了下面的代码，但datagridview的第0列和第1列为空
string Query = "SELECT * FROM people.client";
MySqlConnection myConn = new MySqlConnection(myconnection);
MySqlCommand cmdDataBase = new MySqlCommand(Query, myConn);
MySqlDataAdapter myDataAdapter = new MySqlDataAdapter();
myDataAdapter.SelectCommand = cmdDataBase;
DataTable dbdataset = new DataTable();
myDataAdapter.Fill(dbdataset);
//Set AutoGenerateColumns False
dataGridView1.AutoGenerateColumns = false;
//Set Columns Count
dataGridView1.ColumnCount = 3;
//Add Columns
dataGridView1.Columns[0].HeaderText = "Name";
dataGridView1.Columns[0].DataPropertyName = "FirstName+ ' ' +LastName";
dataGridView1.Columns[1].HeaderText = "Address";
dataGridView1.Columns[1].DataPropertyName = "Street+ '' +City+ '' +State+ '' +Zipcode";
dataGridView1.Columns[2].HeaderText = "Contact Number";
dataGridView1.Columns[2].DataPropertyName = "Contact Number";
dataGridView1.DataSource = dbdataset;
任何帮助，将不胜感激。先感谢您。
SELECT CONCAT(FIRSTNAME, " ", LASTNAME) AS NAME,
CONCAT(STREET, " ", CITY, ", ", STATE, " ", ZIPCODE) AS ADDRESS, PHONE
FROM people.client
这将选择您的两个字段，并用空格分隔它们。
