c#backgroundworker创建datagridview并创建列

我遇到这样一个错误：“无法将任何行添加到没有列的DataGridView控件。必须先添加列。”我在这里做错了什么

        //create datagridview1
          DataGridView dataGridView1 = new DataGridView();

         // DataGridViewColumn column = new DataGridViewTextBoxColumn();

          // Initialize the DataGridView.
          dataGridView1.AutoGenerateColumns = false;
          dataGridView1.AutoSize = true;

          DataGridViewColumn column1 = new DataGridViewTextBoxColumn();
          column1.DataPropertyName = "Column1";
          column1.Name = "title";
          dataGridView1.Columns.Add(column1);

          DataGridViewColumn column2 = new DataGridViewTextBoxColumn();
          column2.DataPropertyName = "Column2";
          column2.Name = "imageurl";
          dataGridView1.Columns.Add(column2);

          DataGridViewColumn column3 = new DataGridViewTextBoxColumn();
          column3.DataPropertyName = "Column3";
          column3.Name = "videourl";
          dataGridView1.Columns.Add(column3);

          DataGridViewColumn column4 = new DataGridViewTextBoxColumn();
          column4.DataPropertyName = "Column4";
          column4.Name = "done";
          dataGridView1.Columns.Add(column4);

试一试

或者如果你想选择coulmn类型

DataGridViewColumn  newCol = new DataGridViewColumn(); // add a column to the grid
DataGridViewCell cell = new DataGridViewCell(); //Specify which type of cell in this column
newCol.CellTemplate = cell;

newCol.HeaderText = "test2";
newCol.Name = "test2";
newCol.Visible = true;
newCol.Width = 40;

gridColors.Columns.Add(newCol);

您还可以看到，

该代码直接位于私有void backgroundWorker1_DoWork（对象发送方，doworkereventargs e）{dataGridView1.Rows.Add（title，“image”，“videourl”，“no”）；@mxadm显示调用

backgroundWorker1.RunWorkerAsync（）的代码

。这看起来像是一个同步问题，可能是在向DataGrdiView添加列之前线程正在运行。@mxadm，奇怪。我验证了这一点，也验证了我的工作。注意：

add

function receivce 2参数。一个是列名，第二个是标题。

DataGridViewColumn  newCol = new DataGridViewColumn(); // add a column to the grid
DataGridViewCell cell = new DataGridViewCell(); //Specify which type of cell in this column
newCol.CellTemplate = cell;

newCol.HeaderText = "test2";
newCol.Name = "test2";
newCol.Visible = true;
newCol.Width = 40;

gridColors.Columns.Add(newCol);
