这是我的代码：

  public List PlayerList { get; set; } public A1_ResultWnd() { InitializeComponent(); //GenerateColumns(); } private void GenerateColumns() { Grid.AutoGenerateColumns = false; DataGridViewColumn miejsce = new DataGridViewColumn(); miejsce.DataPropertyName = "Miejsce"; miejsce.HeaderText = "Miejsce"; miejsce.Name = "miejsceCollumn"; DataGridViewColumn imie = new DataGridViewColumn(); miejsce.DataPropertyName = "Imie"; miejsce.HeaderText = "Imię"; DataGridViewColumn uid = new DataGridViewColumn(); miejsce.DataPropertyName = "UID"; miejsce.HeaderText = "UID"; DataGridViewColumn rasa = new DataGridViewColumn(); miejsce.DataPropertyName = "Rasa"; miejsce.HeaderText = "Rasa"; DataGridViewColumn sex = new DataGridViewColumn(); miejsce.DataPropertyName = "Sex"; miejsce.HeaderText = "Płeć"; DataGridViewColumn klan = new DataGridViewColumn(); miejsce.DataPropertyName = "Klan"; miejsce.HeaderText = "Klan"; DataGridViewColumn strefa = new DataGridViewColumn(); miejsce.DataPropertyName = "Strefa"; miejsce.HeaderText = "Strefa"; DataGridViewColumn status = new DataGridViewColumn(); miejsce.DataPropertyName = "Status"; miejsce.HeaderText = "Status"; Grid.Columns.Add(miejsce); Grid.Columns.Add(imie); Grid.Columns.Add(uid); Grid.Columns.Add(rasa); Grid.Columns.Add(sex); Grid.Columns.Add(klan); Grid.Columns.Add(strefa); Grid.Columns.Add(status); } private void A1_ResultWnd_Shown(object sender, EventArgs e) { GenerateColumns(); Grid.DataSource = PlayerList; //Here the exception occures } 

PlayreList不为空。

  DataGridViewColumn miejsce = new DataGridViewTextBoxColumn(); miejsce.DataPropertyName = "Miejsce"; miejsce.HeaderText = "Miejsce"; miejsce.Name = "miejsceCollumn"; 

  DataGridViewColumn imie = new DataGridViewComboBoxColumn(); imie.DataPropertyName = "Imie"; imie.HeaderText = "Imię"; imie.Name = "imieCollumn" 

  // Prepare the DataViewGrid dataGridView1.Columns.Clear(); // Add each column to the grid according to the data table structure for (int i = 0; i < dataTable.Columns.Count; i++) { DataGridViewColumn dataGridViewColumn = new DataGridViewColumn(); DataGridViewCell dataGridViewCell = new DataGridViewTextBoxCell(); dataGridViewColumn.DataPropertyName = dataTable.Columns[i].ColumnName; dataGridViewColumn.HeaderText = dataTable.Columns[i].ColumnName; dataGridViewColumn.CellTemplate = dataGridViewCell; dataGridViewColumn.Name = dataTable.Columns[i].ColumnName; dataGridView1.Columns.Add(dataGridViewColumn); } // Set the DataSource for the binding bindingSource1.DataSource = dataTable; // Prevent unwanted columns autogeneration dataGridView1.AutoGenerateColumns = false; // Provide the binding to the DataGridView dataGridView1.DataSource = bindingSource1; 

 DataGridViewColumn c = new DataGridViewColumn(); c.Name = "ColumnName"; c.HeaderText = "DisplayText"; c.AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells; c.CellTemplate = new DataGridViewTextBoxCell(); dataGridView1.Columns.Add(c);
