C# “不支持关键字：'pdatasource'

关键字“不受支持”是什么意思：“pdatasource.As我正在努力找出到底是什么问题？”

        InitializeComponent();
        connString = "PData    Source=.\\SQLEXPRESS;AttachDbFilename=C:\\Users\andrew\\Documents\\Vinyl0.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
        query = "SELECT * FROM Record";
        dAdapter = new SqlDataAdapter(query, connString);
        dTable = new DataTable();
        cBuilder = new SqlCommandBuilder(dAdapter);
        cBuilder.QuotePrefix = "[";
        cBuilder.QuoteSuffix = "]";
        myDataView = dTable.DefaultView;
        dAdapter.Fill(dTable);
        BindingSource bndSource = new BindingSource();
        bndSource.DataSource = dTable;
        this.dataGridView1.DataSource = bndSource;
        for (int q = 0; q <= dataGridView1.ColumnCount - 1; q++)
        {

您的连接字符串有输入错误。应该是

connString = "Data Source=.\\SQLEXPRESS;AttachDbFilename=C:\\Users\\andrew\\Documents\\Vinyl0.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";
              ^-----  not "PData    Source"

您的SqlDataAdapter似乎无法识别PData字段

我也不认识，你有没有试着去掉写着PData的部分？

你的连接字符串不正确

将PData源更改为数据源或服务器，应该可以

请参阅本文和本文，了解基于您的版本/数据适配器的连接字符串的构造。
