How to select a row in DataGridView

the C++.Net solution is :
this->dataGridView1->ClearSelection();

this->dataGridView1->SelectionMode = DataGridViewSelectionMode::FullRowSelect;
this->dataGridView1->Rows[i]->Selected=true;
this->dataGridView1->CurrentCell=this->dataGridView1->Rows[i]->Cells["ColumnName"];
这几步的作用分别是：
清除当前选择；设定选择模式为整行选取；设定某行为选定；设定当前网格
