我正在尝试打开驱动器上的一个特定文本文件的文本文件,并且我不想包含文本框或查看/浏览要打开的文件。我只希望它只自动打开磁盘驱动器上指定的文本文件而不通过文本框,单击按钮后驱动器中的特定文本文件应自动打开

下面是这样的:

private void button1_Click(object sender, EventArgs e)
{
  c:\users\Dickson\Documents\oracle.txt;//
}

我希望它在我单击按钮时打开此处指定的文件。

如果您想使用记事本或任何其他默认程序打开 txt 文件,您可以执行以下操作:

Process.Start(@"C:\Users\Dickson\Documents\oracle.txt");

如果要读取代码中的文件,可以这样做:

var txtContent = File.ReadAllText(@"C:\Users\Dickson\Documents\oracle.txt");

您还可以使用以下代码读取文件的内容:

FILE *infile;
infile = fopen("file_name", "r");

我不确定这是否是你的意思,但是..

也许像

static class program
{
  static void Main()
  {
    System.Windows.Forms.Application.Run(new frmMain());
  }
}

public class frmMain : Form
{
  private System.Windows.Forms.Label lblText;
  private System.Windows.Forms.Button btnLoadText;

  public frmMain()
  {
    InitializeComponent();
  }

  private void InitializeComponent()
  {
    this.lblText = new System.Windows.Forms.Label();
    this.lblText.AutoSize = true;
    this.lblText.Dock = System.Windows.Forms.DockStyle.Top;
    this.lblText.Font = new System.Drawing.Font("Microsoft Sans Serif", 14.25F, System.Drawing.FontStyle.Bold, System.Drawing.GraphicsUnit.Point, ((byte)(0)));
    this.lblText.Location = new System.Drawing.Point(0, 0);
    this.lblText.Name = "lblText";
    this.lblText.Size = new System.Drawing.Size(170, 24);
    this.lblText.TabIndex = 0;
    this.lblText.Text = "";
    this.Controls.Add(this.lblText);

    this.btnLoadText = new System.Windows.Forms.Button();
    this.btnLoadText.Location = new System.Drawing.Point(339, 24);
    this.btnLoadText.Name = "btnLoadText";
    this.btnLoadText.Size = new System.Drawing.Size(75, 23);
    this.btnLoadText.TabIndex = 29;
    this.btnLoadText.Text = "Load Text";
    this.btnLoadText.UseVisualStyleBackColor = true;
    this.btnLoadText.Dock = System.Windows.Forms.DockStyle.Bottom;
    this.Controls.Add(this.btnLoadText);
    this.btnLoadText.Click += new System.EventHandler(this.btnLoadText_Click);          
  }

  private void btnLoadText_Click(object sender, EventArgs e)
  {
    StreamReader streamReader = new StreamReader("test.txt");
    string text = streamReader.ReadToEnd();
    streamReader.Close();
    this.lblText.Text = text;
  }
}
