System.OutOfMemoryException：Out of Memory Error using [英] System.OutOfMemoryException: Out Of Memory Error Using

问题描述

任何人都可以帮我紧急。



我有一个压缩和解压缩时我的数据表中的lakh记录和序列化之后我得到类型'System.OutOfMemoryException'的异常被抛出



我正在使用WCF + WPF



我的代码是

  public   static  MemoryStream DataTableSerialization（DataTable dtSearchDataTable）
 {
 System.IO.MemoryStreamstream = newSystem.IO.MemoryStream（）; 
 
 System.Runtime.Serialization.IFormatterformatter = newSystem.Runtime.Serialization.Formatters.Binary.BinaryFormatter（）; 
  byte  [] bytes =  null ; 
 
 MemoryStream memory =  new  MemoryStream（）; 
 
  try  
 {
 dtSearchDataTable.RemotingFormat = SerializationFormat.Binary; 
 
 formatter.Serialize（stream，dtSearchDataTable）;  //  这里我收到错误 
 bytes = stream.ToArray（）; 
 
 使用（vargzip = newGZipStream（memory，CompressionMode.Compress， true ） ）
 {
 gzip.Write（bytes， 0 ，bytes.Length）; 
} 
 
 memory.Position =  0 ; 
 
  //   ---为了在客户端反序列化期间启用阅读选项，我们需要设置Position = 0  
} 
  catch （Exceptionex）
 {
} 
  finally  
 
 {
 stream.Dispose（）; 
 MinimizeMemory（）; 
} 
 
 返回内存; 
} 

我的Webconfig（WCF）



< pre lang =HTML> < opentimeout receivetimeout = 04:10:00 sendtimeout = 04:01:00 >

添加了代码标记。甚至没有尝试正确格式化web.config部分，但这是一个不完整的片段。请排序。

解决方案

Hi,

Can any one please help me its urgent.

I am having one lakh record in my datatable while compress and de compress and after serialize i am getting Exception of type 'System.OutOfMemoryException' was throw

I AM USING WCF+WPF

My Code is

public static MemoryStream DataTableSerialization(DataTable dtSearchDataTable)
{
    System.IO.MemoryStreamstream = newSystem.IO.MemoryStream();
 
    System.Runtime.Serialization.IFormatterformatter = newSystem.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
    byte[] bytes = null;

    MemoryStream memory = new MemoryStream();  

    try
    {
        dtSearchDataTable.RemotingFormat = SerializationFormat.Binary;
        
        formatter.Serialize(stream, dtSearchDataTable);//Here i am getting error 
        bytes = stream.ToArray();
        
        using (vargzip = newGZipStream(memory, CompressionMode.Compress, true))
        {
            gzip.Write(bytes, 0, bytes.Length);
        }
        
        memory.Position = 0; 
        
        // ---  In order to enable reading option during Deserialzation on client side we need to set Position = 0
        }
    catch(Exceptionex)
    {  
    } 
    finally
    
    {
        stream.Dispose();
        MinimizeMemory();
    }            

    return memory;
}

My Webconfig(WCF)

<opentimeout receivetimeout="04:10:00" sendtimeout="04:01:00">
bypassProxyOnLocal="false"
hostNameComparisonMode="StrongWildcard"           
maxBufferSize="2147483647"
maxBufferPoolSize="2147483647"
maxReceivedMessageSize="2147483647"    
messageEncoding="Text"
textEncoding="utf-8"
useDefaultWebProxy="true"      
allowCookies="false">
<readerQuotasmaxdepth maxstringcontentlength="2147483647" maxarraylength="2147483647">
 
maxBytesPerRead="4096"maxNameTableCharCount="16384"/>
                 bindingname="SearchBinding"closeTimeout="04:01:00">
</readerquotasmaxdepth>
</opentimeout>

- Edit MK -
Added code tags. Didn't even try to correctly format the web.config part though, it's an incomplete snippet. Please sort that out.
