最初，此代码接收的错误表明JsonScriptSerializer可能存在文件大小限制。我的问题是：csv的内容是否有限制？例如，尝试转换为Json的csv包含23列和20000行。如果我将列缩小到7并将行缩小到1000，则转换运行并转换为Json。
此处the original code 尝试 {
if (FileUpload1.PostedFile.FileName != string.Empty)
{
string[] FileExt = FileUpload1.FileName.Split('.');
string FileEx = FileExt[FileExt.Length - 1];
if (FileEx.ToLower() == "csv")
{
string SourcePath = Server.MapPath("Resources//" + FileUpload1.FileName);
FileUpload1.SaveAs(SourcePath);
string Destpath = (Server.MapPath("Resources//" + FileExt[0] + ".json"));
StreamWriter sw = new StreamWriter(Destpath);
var csv = new List<string[]>();
var lines = System.IO.File.ReadAllLines(SourcePath);
foreach (string line in lines)
csv.Add(line.Split(','));
string json = new
System.Web.Script.Serialization.JavaScriptSerializer().Serialize(csv);
sw.Write(json);
sw.Close();
TextBox1.Text = Destpath;
MessageBox.Show("File is converted to json.");
}
else
{
MessageBox.Show("Invalid File");
}
}
else
{
MessageBox.Show("File Not Found.");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
