从解析字符串值的单行条件语句将null传递给DataTable

DataTable dataTable = new DataTable();
dataTable.Columns.Add("ColumnName", typeof(string));
DataRow dataRow = dataTable.NewRow();
dataRow["ColumnName"] = null;
dataTable.Rows.Add(dataRow);

string inputString = "Value1,Value2,Value3";
string[] values = inputString.Split(',');
DataTable dataTable = new DataTable();
dataTable.Columns.Add("Column1", typeof(string));
dataTable.Columns.Add("Column2", typeof(string));
dataTable.Columns.Add("Column3", typeof(string));
DataRow dataRow = dataTable.NewRow();
dataRow["Column1"] = values[0];
dataRow["Column2"] = values.Length > 1 ? values[1] : null;
dataRow["Column3"] = values.Length > 2 ? values[2] : null;
dataTable.Rows.Add(dataRow);
