从字符串生成DataGridView列

string columnInfo = "Name:string:100,Age:int:50,DOB:date:80";

// 解析字符串
string[] columnInfos = columnInfo.Split(',');
List<DataGridViewColumn> columns = new List<DataGridViewColumn>();

foreach (string info in columnInfos)
{
    string[] columnData = info.Split(':');
    string columnName = columnData[0];
    string dataType = columnData[1];
    int width = int.Parse(columnData[2]);

    // 创建列对象
    DataGridViewColumn column;
    if (dataType == "string")
    {
        column = new DataGridViewTextBoxColumn();
    }
    else if (dataType == "int")
    {
        column = new DataGridViewTextBoxColumn();
        // 设置只允许输入数字
        column.DefaultCellStyle = new DataGridViewCellStyle() { Format = "N0" };
    }
    else if (dataType == "date")
    {
        column = new DataGridViewTextBoxColumn();
        // 设置日期格式
        column.DefaultCellStyle = new DataGridViewCellStyle() { Format = "yyyy-MM-dd" };
    }
    else
    {
        // 其他数据类型的处理
        continue;
    }

    column.Name = columnName;
    column.HeaderText = columnName;
    column.Width = width;

    // 添加列到DataGridView
    columns.Add(column);
}

dataGridView1.Columns.AddRange(columns.ToArray());
