NuGet installation SqlSugar
New DbContext class file under 1.Model
public class DbContext
{
public DbContext()
{
Db = new SqlSugarClient(new ConnectionConfig()
{
ConnectionString = "server=localhost;uid=root;pwd=woshishui;database=test",
DbType = DbType.MySql,
InitKeyType = InitKeyType.Attribute,//从特性读取主键和自增列信息
IsAutoCloseConnection = true,//开启自动释放模式和EF原理一样我就不多解释了
});
//调式代码 用来打印SQL
Db.Aop.OnLogExecuting = (sql, pars) =>
{
Console.WriteLine(sql + "\r\n" +
Db.Utilities.SerializeObject(pars.ToDictionary(it => it.ParameterName, it => it.Value)));
Console.WriteLine();
};
}
//注意：不能写成静态的，不能写成静态的
public SqlSugarClient Db;//用来处理事务多表查询和复杂的操作
public SimpleClient<uploading> uploadingdb { get { return new SimpleClient<uploading>(Db); } }//用来处理Student表的常用操作
}
2. built uploading entity class
[SugarTable("uploading")]
public class uploading
{
//指定主键和自增列，当然数据库中也要设置主键和自增列才会有效
[SugarColumn(IsPrimaryKey = true, IsIdentity = true)]
public int id { get; set; }
public string name { get; set; }
public string path { get; set; }
}
Built UploadingManager under 3.Manager file
class UploadingManager : DbContext
{
public List<uploading> Query()
{
try
{
List<uploading> data = Db.Queryable<uploading>()
.Select(f => new uploading
{
name = f.name,
path = f.path
})
.ToList();
return data;
}
catch (Exception e)
{
Console.WriteLine(e);
throw;
}
}
public List<string> GetName(string name)
{
List<string> data = Db.Queryable<uploading>()
.Where(w=>w.name== name)
.Select(f => f.path)
.ToList();
return data;
}
}
Form Load Form1_Load
1. Read the database field name and assign
private void Form1_Load(object sender, EventArgs e)
{
List<uploading> data = uploading.Query();
foreach (var data1 in data)
{
comboBox1.Items.Add(data1.name);
}
comboBox1.SelectedIndex = 0;
}
2.comboBox event triggers a query to upload path
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
List<string> data = uploading.GetName(comboBox1.Text);
for (int i = 0; i < data.Count; i++)
{
textBox1.Text = data[0];
}
}
3. Upload event triggers
private void Button1_Click(object sender, EventArgs e)
{
string path = textBox1.Text;
CopyDirs(textBox3.Text,
path);
}
private void CopyDirs(string srcPath, string aimPath)
{
try
{
// 检查目标目录是否以目录分割字符结束如果不是则添加
if (aimPath[aimPath.Length - 1] != System.IO.Path.DirectorySeparatorChar)
{
aimPath += System.IO.Path.DirectorySeparatorChar;
}
// 判断目标目录是否存在如果不存在则新建
if (!System.IO.Directory.Exists(aimPath))
{
System.IO.Directory.CreateDirectory(aimPath);
}
// 得到源目录的文件列表，该里面是包含文件以及目录路径的一个数组
// 如果你指向copy目标文件下面的文件而不包含目录请使用下面的方法
// string[] fileList = Directory.GetFiles（srcPath）；
string[] fileList = System.IO.Directory.GetFileSystemEntries(srcPath);
// 遍历所有的文件和目录
foreach (string file in fileList)
{
// 先当作目录处理如果存在这个目录就递归Copy该目录下面的文件
if (System.IO.Directory.Exists(file))
{
CopyDir(file, aimPath + System.IO.Path.GetFileName(file));
DisplaylistboxMsg("上传成功");
}
// 否则直接Copy文件
else
{
System.IO.File.Copy(file, aimPath + System.IO.Path.GetFileName(file), true);
DisplaylistboxMsg("上传成功");
}
}
}
catch (Exception e)
{
DisplaylistboxMsg("上传失败" + e.Message);
}
}
4. Download event triggers
private void Button2_Click(object sender, EventArgs e)
{
CopyDir(@"\\10.55.2.3\mech_production_line_sharing\Test\" + textBox2.Text, textBox4.Text);
}
private void CopyDir(string srcPath, string aimPath)
{
// 检查目标目录是否以目录分割字符结束如果不是则添加
if (aimPath[aimPath.Length - 1] != System.IO.Path.DirectorySeparatorChar)
{
aimPath += System.IO.Path.DirectorySeparatorChar;
}
// 判断目标目录是否存在如果不存在则新建
if (!System.IO.Directory.Exists(aimPath))
{
System.IO.Directory.CreateDirectory(aimPath);
}
// 得到源目录的文件列表，该里面是包含文件以及目录路径的一个数组
// 如果你指向copy目标文件下面的文件而不包含目录请使用下面的方法
// string[] fileList = Directory.GetFiles（srcPath）；
string[] fileList = System.IO.Directory.GetFileSystemEntries(srcPath);
// 遍历所有的文件和目录
foreach (string file in fileList)
{
// 先当作目录处理如果存在这个目录就递归Copy该目录下面的文件
if (System.IO.Directory.Exists(file))
{
CopyDir(file, aimPath + System.IO.Path.GetFileName(file));
DisplaylistboxMsg("下载成功");
}
// 否则直接Copy文件
else
{
System.IO.File.Copy(file, aimPath + System.IO.Path.GetFileName(file), true);
DisplaylistboxMsg("下载成功");
}
}
}
