试试！

It's not so hard to do it. All you need to do is to loop through the rows collection ;)

Try!

//使用Windows应用程序并添加ID为dataGridView1的DataGridView。

//按下按钮并在其点击事件下面放置代码。

//希望它有所帮助。 :) .... Prasad





DataTable dt;



private void Form1_Load（object sender，EventArgs e）

{

dt = new DataTable（）;

dt .Columns.Add（Col1）;

dt.Columns.Add（Col2）;

dt.Columns.Add（Col3）;

dt.Columns.Add（Col4）;



DataRow dr = dt.NewRow（）;

dr [Col1] =val1;

dr [Col2] =val2;

dr [Col3] =val3;

dr [Col4] =val4;



dt.Rows.Add（dr）;



dataGridView1.DataSource = dt;

}



private void button1_Click（object sender，EventArgs e）

{

string temp;



for（int i = 0; i< dataGrid View1.Rows.Count; i ++）

{

//显示所有值

MessageBox.Show（Convert.ToString（

dataGridView1） .Rows [i] .Cells [col1]。Value +\ n+

dataGridView1.Rows [i] .Cells [col2]。Value +\ n +

dataGridView1.Rows [i] .Cells [col3]。Value）

）;

//获得2个值单个字符串

temp = dataGridView1.Rows [i] .Cells [col1]。值+

dataGridView1.Rows [i] .Cells [col2]。价值;



}

}

// Take Windows application and add DataGridView with id "dataGridView1".
// Take button and place below code on its click event.
// Hope it helps. :) ....Prasad


DataTable dt;

private void Form1_Load(object sender, EventArgs e)
{
dt = new DataTable();
dt.Columns.Add("Col1");
dt.Columns.Add("Col2");
dt.Columns.Add("Col3");
dt.Columns.Add("Col4");

DataRow dr = dt.NewRow();
dr["Col1"] = "val1";
dr["Col2"] = "val2";
dr["Col3"] = "val3";
dr["Col4"] = "val4";

dt.Rows.Add(dr);

dataGridView1.DataSource = dt;
}

private void button1_Click(object sender, EventArgs e)
{
string temp;

for (int i = 0; i < dataGridView1.Rows.Count; i++)
{
// To show all values
MessageBox.Show(Convert.ToString(
dataGridView1.Rows[i].Cells["col1"].Value + "\n" +
dataGridView1.Rows[i].Cells["col2"].Value + "\n" +
dataGridView1.Rows[i].Cells["col3"].Value)
);
// To get 2 values in single string
temp = dataGridView1.Rows[i].Cells["col1"].Value +
dataGridView1.Rows[i].Cells["col2"].Value;

}
