将.txt文件作为Blob从ASP.Net存储到Mysql MVC3

Question

目前我正在使用ASP.NET MVC 3项目。我需要将文本（.txt）文件作为Blob存储到MySQL中。 MySQL对我来说是新的。

Answer 1

应该像this（的ConnectionString应修改）：

string filePath = @"C:\\MyFile.ext"; 

//A stream of bytes that represnts the binary file 
FileStream fs = new FileStream(filePath, FileMode.Open, FileAccess.Read); 

//The reader reads the binary data from the file stream 
BinaryReader reader = new BinaryReader(fs); 

//Bytes from the binary reader stored in BlobValue array 
byte[] BlobValue = reader.ReadBytes((int)fs.Length); 

fs.Close(); 
reader.Close(); 

SqlConnection BlobsDatabaseConn = new SqlConnection("Data Source = .; Initial Catalog = BlobsDatabase; Integrated Security = SSPI"); 
SqlCommand SaveBlobeCommand = new SqlCommand(); 
SaveBlobeCommand.Connection = BlobsDatabaseConn; 
SaveBlobeCommand.CommandType = CommandType.Text; 
SaveBlobeCommand.CommandText = "INSERT INTO BlobsTable(BlobFileName, BlobFile)" + "VALUES (@BlobFileName, @BlobFile)"; 

SqlParameter BlobFileNameParam = new SqlParameter("@BlobFileName", SqlDbType.NChar); 
SqlParameter BlobFileParam = new SqlParameter("@BlobFile", SqlDbType.Binary); 
SaveBlobeCommand.Parameters.Add(BlobFileNameParam); 
SaveBlobeCommand.Parameters.Add(BlobFileParam); 
BlobFileNameParam.Value = filePath.Substring(filePath.LastIndexOf("\\") + 1); 
BlobFileParam.Value = BlobValue; 
try 
{ 
    SaveBlobeCommand.Connection.Open(); 
    SaveBlobeCommand.ExecuteNonQuery(); 
    MessageBox.Show(BlobFileNameParam.Value.ToString() + " saved to database.","BLOB Saved", MessageBoxButtons.OK, MessageBoxIcon.Information); 
} 

catch(Exception ex) 
{ 
    MessageBox.Show(ex.Message, "Save Failed", MessageBoxButtons.OK, MessageBoxIcon.Error); 
} 

finally 
{ 
    SaveBlobeCommand.Connection.Close(); 
}
