Datagridview刪除重複的行

Question

我需要你的幫助從datagrid中刪除重複。我做了這個，

foreach (DataGridViewRow viewrow1 in this.dataGridView1.Rows) 
     { 

      DataRowView row1 = viewrow1.DataBoundItem as DataRowView; 
      if(row1 != null){ 
       foreach (DataGridViewRow viewRow2 in this.dataGridView2.Rows) 
       { 
        DataRowView row2 = viewRow2.DataBoundItem as DataRowView; 
        if (row2 != null && row1.Row["test"].Equals(row2.Row["test"])) 
        { 
         row2.Row.Delete(); 

        } 

       } 
      } 

     } 

它的工作原理，但不會刪除1行。

Thx尋求幫助。

foreach (DataGridViewRow viewrow1 in this.dataGridView1.Rows) 
    { 

     DataRowView row1 = viewrow1.DataBoundItem as DataRowView; 
     if(row1 != null){ 
      foreach (DataGridViewRow viewRow2 in this.dataGridView2.Rows) 
      { 
       DataRowView row2 = viewRow2.DataBoundItem as DataRowView; 
       if (row2 != null && row1.Row["test"].Equals(row2.Row["test"])) 
       { 
        dataGridView1.Rows.Remove(row2); 

       } 

      } 
     } 

    }
