C# DataGridView 与 datatable 之间数据传递

一、 DATAGRIDVIEW 数值传递给datable

int cn = dataGridView1.Rows.Count; int col = dataGridView1.ColumnCount; for (int j = 0; j < col;j++ ) { DataColumn dc = new DataColumn(dataGridView1.Columns[j].Name.ToString()); dt.Columns.Add(dc); } for (int m = 0;m< cn; m++) { DataRow dr = dt.NewRow(); for (int n = 0; n < col;n++ ) { dr[n] = Convert.ToString(dataGridView1.Rows[m].Cells[n].Value); }

dt.Rows.Add(dr);

}

二、datatable 数值 传递到datagridview

 DataTable dt = new DataTable();

for (int x = 0; x < dt.Rows.Count; x++) {

bool yn = Convert.ToBoolean(Convert.ToInt32(dt.Rows[x][0].ToString())); dataGridView1.Rows.Add(yn, (x + 1).ToString(), (dt.Rows[x][2].ToString()), (dt.Rows[x][3].ToString()), (dt.Rows[x][4].ToString())); }
